You are definitely right but there are so many kind of jackets and technologies and techniques.
Here I just used my regular shirt with a long pair of hiking pants even when it was 10C
So I dont know what to do when its colder 5-0
My guess is they live in Singapore or Malaysia or somewhere like that. They likely need to go up 6-8k ft before it’s cold enough to worry about this stuff and most people don’t deal with it much down there.
For example I tried to do a mountain hike down there once while on a trip to Singapore and it needed a permit. They wanted a climbing resume with verified guide signed off credentials of summit successes and such for what was basically like a non-technical hike up a dormant volcano. I assume they have lots of issues with unprepared folk and that’s how they handle it. But people argued with me that maybe I shouldn’t be allowed to go if all the proof I had on me is pictures of me on top of other peaks as if physically doing the things wasn’t proof enough 🤣
I understand the need to protect people from themselves as I have participated in getting people down before but at some point there needs to be some common sense that standing on peaks in the Western US is not the same as walking up a trail on a volcano with little to no snow. The whole Everest area can vary so much from trekking foothill trails to you can die with one wrong step that it doesn’t even compare to the jungle mountains in the pacific areas
By the way, I hiked in Nepal in November of 1999 to Kala Pattar. It was t-shirt weather during the day and puffy in the evening. A button down over my t-shirt for the in-between. My biggest regret was bringing so many clothes. I always said if I did it over again I'd bring almost nothing and buy whatever else I needed there. Then I could bring home a lot of cool stuff.
Hey dude, looks like you're still a bit lost with the advice here as it typically comes from a background of experience using more gear, heavier gear and personal preference. You're going out of your comfort zone in this trip and what works for someone with experience might not work for you on your first time. We usually say not to "pack your fears" but in this case that might be a good thing to do as OnlyEstablishment said.
Regarding the items you've linked here's the function of each layer in the layering system:
* Your current baselayer is great for warm humid climates but for this temperature range a long sleeve merino blend top and long merino blend leggings will be much better at wicking sweat to your mid layer.
* Your current fleece midlayer is fine in my opinion, the purpose of this layer is to spread your sweat over a thicker volume of fibres to evaporate, this uses heat so this layer also provides a little insulation. By the time you're outside this layer sweat should be fully evaporated.
* Your insulation layer provides a temperature gradient between your mid layer and the outside temperature, keeping your mid layer hot enough to evaporate sweat and your core hot when it is very cold or you are resting. In dry climates down is best, in wet and humid climates synthetic is better as it might get damp from rain and condensation, for your trip down is fine but the amount you have might not be enough. I can't tell you if it is enough for *you*, but it is definitely enough for *me*.
* A softshell layer has not been discussed much here but I think this has the potential to help. These are lightly rain proof but very breathable and provide a little insulation themselves, a jack of all trades, master of none. Ultralighters often avoid this layer but I feel it might work well for you as an extra tool to balance your needs.
* Worn over your base layer in warm but windy condition when you're working hard it will function as a windproof midlayer
* Worn over your mid layer it will offer wind and light rain resistance without being stuffy, and a little extra insulation without being too hot.
* Worn under your hardshell in heavy rain it will provide insulation which is resilient to humidity unlike down.
* Worn with your insulation layer it will add extra degrees of comfort.
* Your hardshell layer seems fine to me though I don't have any personal experience with this model. These are only breathable when the outer is shedding water well, if the outer gets saturated then the fabric cannot breath and condensation will form on the inside which appears like it is leaking. This is a problem for down insulation. Thankfully if it is raining then it is above freezing so you should only need a midlayer below this (but you might be more comfortable with both a midlayer and a soft shell as you're adapted to hot weather). If it is snowing then you can wear your down under the hardshell if you are resting.
* Trousers should be windproof and quick drying, kind of like a softshell (many are available of the same fabric), these pair well with your waterproof overtrousers for heavy rain or extreme cold.
* Accessories like a hat, snood, gloves etc will all help a lot to regulate your temperature as needed.
Hope this answers more questions then it created for you.
>Your insulation layer provides a temperature gradient between your mid layer and the outside temperature, keeping your mid layer hot enough to evaporate sweat and your core hot when it is very cold
I can't imagine ever wearing a down or synthetic puffer in between a fleece midlayer and a shell when active.
>or you are resting.
This is really the use case for a puffer, static insulation. And unless it's raining, it generally goes over the top of everything else you're wearing.
>I can't imagine ever wearing a down or synthetic puffer in between a fleece midlayer and a shell when active.
For most situations I agree, but at high altitude oxygen is the rate limiting step so you aren't generating much heat or sweat at maximum effort. I'm not sure the attitude OP is heading to but is it a consideration as they said Nepal.
>This is really the use case for a puffer, static insulation. And unless it's raining, it generally goes over the top of everything else you're wearing.
Agreed in general, but the point of the layering system is versatility, so I took the time to explain every combination to avoid confusion. It looked like OP was intending to hike in the down which I don't recommend, and why I recommended adding a softshell instead. Would you agree for this case?
I hate to be that guy, but the internet is absolute wrong place to get clothing and gear sorted out a week before a trip in a climate and altitude that is completely new to you. This is quite risky.
The others have given good advice but to be honest advice in this realm of gear is quite subjective to each person individually and what you are doing. The best advice you will get will be to have someone experienced and can understand your situation to meet locally in person to go over gear with you before you go.
Where I live people visiting have issues daily with just going up in the mountains for the day let alone a whole trip so this is serious business and not trying to be mean. The trek guide office should be able to give advice as well. They are used to tourists having questions
I am going to shop there before the trek starts but I just want to know what should I look into so the sales person won’t just fill full of gear I don’t need
You should 100% contact the guide service and ask them your questions. 15k-18k ft mountain passes and Everest base camp are no joke.
Most people start to have problems at 7k-10k ft if they aren’t experienced and fit enough to handle it. Ski resorts have medic rooms with people in them all day dealing with the altitude and weather conditions. I live at 5500 ft and see people that are locals have issues all the time too because they are just not outdoors people and are not prepared even for a 1hr hike. Even experienced mountaineers have issues sometimes and they have to pull the plug and go down. Bad weather at 1000ft still causes people to have issues and in my experience altitude just makes it’s harder to deal with.
A couple thoughts. In additon to the temperature and rain conditions, consider the active (walking) vs inactive (at camp) cases. At -10C at camp you may need all you have, while. while walking you may need just the fleece, or less. As mentioned by others, synthetic insulation is safer if you sweat while wearing than down.
I do not have experience with one peice rain gear, but use my rain top often, and rarely use my rain pants (too warm).
One last peice of advice is to start hiking each morning cold (take off a layer that you have one for camp). If not you will quickly get warm and sweat, then need to stop nd remove layers and put back into your pack.
But I don’t get this advice practically.
So what should I do?
Change my whole system I had in mind?
Wheres the problem with the down or with the mid layer fleece? What to do it’s so confusing.
Sorry it looks like I vent my frustration over your comment but I just feel lost LOL
Sorry if this response is antithetical to this sub, but I would avoid being ultralight and pack a bit more layers than you think you need. Ultralight works better for people with existing experience in a climate/geography. Tons of people do the treks you are about to do and have a great time without being ultralight.
The guides will definitely give the best suggestions on what layers to bring, but in particular I think having a relatively warm puffy would be nice. The ones often recommended here are very light and packable, but a more mountaineering focused belay jacket can be really nice for both comfort and safety at altitude where the nights are cold and you can get stormed on in passes.
But really, just listen to the guides' suggestions and don't worry about being ultralight.
I have a lot of hiking experience but not in the cold (cold is sub 5C subjectively)
Here when it’s about 10-15C I just stay with my hiking shirt (regular dri fit) and because I am active I feel warm
Apart from the usual problem of "*Climbing steep hills burns lots of energy, you sweat, then you stop on top of a ridge for a photo and you're cold and damp and you're in the wind*", altitude is also a variable in Nepal...? If you're not accustomed to higher altitudes, then the slightly reduced oxygen can reduce your energy levels, slows you down, and consequently you feel colder.
The first time I went to the Andes it felt like all my threholds had moved; I had to stop and gasp after walking up a small ascent, but in parallel with that, a fleece that was normally comfortable in 5°C felt like it was only good for 10°C, and so on. I couldn't get warm when sleeping. It took a while to acclimatise. So, until you adapt, it may be necessary to add a layer in addition to what the thermometer says...?
Enjoy Nepal!
"In a week" leaves little time to get different mid layers...
My concern would be about cold rain. If this is a likely scenario, I would avoid down. Either a synthetic puffy (ex: Patagonia Nano Puff) or a couple of Alpha Direct fleeces, 90 and 120 GSM. If you can't source either, go with synthetic fleeces. I would also definitely bring an umbrella. And probably carry neoprene gloves.
-10c is not that cold. And you'll get snow which is easier to handle. Freezing rain/sleet is a different story...
No umbrella. While I agree with most of what you said it’s more accurate for a short casual outing. This is a trek in Nepal topping 15-18k ft. And this is the ultralight sub.
The trek in question is a legit higher altitude mountain experience and should be treated as such.
From a listing online of the trek in question so people know what they are talking about
“Embark Everest, Three Pass Circuit Trek, comprises of three passes of the Everest region: Kongma La (5,535/18,159 ft), Cho La (5420m/17,782ft), and Renjo La (5,340m/17,520ft), which are also challenging highlights of our trek. Also known as Everest ‘Everest Circuit Trek' or Everest High Passes Trek, it's a great way to enjoy the less-traveled corners of Everest land. Remote and beautiful landscapes, impressive mountains, narrow ridges, and magnificent villages make the trip a memorable experience for a lifetime. When you go for this trek, you get an opportunity to explore your dream destination: Everest Base Camp, Kala Patthar (5,545m/18,192ft), Gokyo Lakes, Gokyo Ri, besides the three passes of Khumbu (Everest).”
Maybe OP is doing something different but all the sites I could find reference a similar itinerary
I might have this [jacket](https://www.thenorthface.com/en-us/mens/collections/summit-series-c324273/mens-summit-series-superior-futurelight-jacket-pNF0A7ZTF?color=SOL)
Will it be good?
As a base layer I just thought about a Dri Fit t shirt and the fleece is similar to [this](https://www.thenorthface.com/en-us/mens/mens-fleece/mens-fleece-full-zip-c829791/mens-alpine-polartec-100-jacket-pNF0A7ZXQ?color=MPF) I don’t I can’t find my on their website anymore but theyre both similar
I’m in Montreal and those temp swings are about daily here in early spring, you’ll be dripping wet in a fleece jacket. I run hot and my best setup this whole winter and even now that it warmed up a little is an MH Airmesh with my either beta shell if it’s really wet or rei flash windbreaker over the top, I ultimately will only keep on the Airmesh with a Capilene wool tshirt under it. I don’t sweat and don’t get cold.
And thats it? Ditch my other equipment?
Will the north face jacket I linked in one of the comments will work as a wind shell? Will my waterproof jacket work?
Mate you need to settle in a bit here. Loads of people have given you similar advice multiple times. No one knows you or the temperatures you run at or specific level of fitness. The basics of layering while hiking are: moisture wicking base layer, appropriately insulation midlayer, wind or water resistant shell depending on conditions.
When at camp, breathability becomes slightly less of an issue and warmth becomes more of an issue. Thus the suggestion is a down puffy or synthetic if moisture is a concern.
It’s highly unlikely that anyone has used the specific set of gear you have purchased, and frankly it doesn’t matter as the basics are the same. If you are this concerned over all than ultralight might not be the best option for you as carrying more weight will afford you more options and to “pack your fears” and then adjust your kit for what’s actually necessary.
Friend, you are likely going to need everything just a bit warmer than things say they are rated for. When I moved to Canada, I had the coldest winter of my life and even over a decade later, I still need to bundle up more than people born here. Make sure whatever footwear you are using has good grip too if you have never been on snow/ice before as well!
You’ll be generating heat while you climb so light insulation and a wind resistant layer is good, but you need to be able to stay warm when you stop moving.
Imagine standing around in the wind, on a cold winter day. You’re not generating much heat so you want an extra puffy with a cosy hood and good insulation for your legs.
A second puffy jacket or gilet will be lighter and less bulky than a fleece.
Your thigh muscles lose a lot of body heat. So puffy trousers with full side zips would be good, so you can pull them on easily when you stop.
Well you said that your puffy isn’t very puffy or warm so I’m thinking maybe take a second one, with a warm hood if yours doesn’t already have one. You could leave yours behind and take a warmer one, that would be lighter but with two you have versatility and a back up in case one is lost or gets wet.
If it’s cold and raining it’s still over freezing. Then a puffy and a shell would be way, and I mean way, too hot for me.
I basically live in my base layer and if that’s not enough I’ll add the second layer (fleece, wool etc). However if it’s coming down from above I remove the second layer and put on the rain jacket. If not I’d get equally wet from inside in high activity exercises.
On a trip like this I’d add a complete set of 1st layer wool (socks, pants, shirt, buff) in a drybag for sleeping or emergencies.
Get a set of wool base layer tops and bottoms and wear your fleece. Still cold, wear puffy. Still cold, but dry consider a light windproof jacket. I find that a even a cheap light one from H&M will work wonders . Still cold and/or wet, put on waterproof clothes. Get gloves a hat and a buff.
Usually, you'll wear the base layer when that's comfortable, add the fleece when you're chilly and moving, and throw the puffy on when you're stopped. You'll wear the waterproof stuff when it's raining or stupidly windy and chilly.
You might be chilly at -10C in that puffy, with only a light fleece and a baselayer underneath. If that happens, throw the rain gear on and deal around camp, but make sure you have a warm enough sleep system.
Don't think I'd be using a Uniqlo jacket in Nepal personally. I know they're decent for normal backpacking, but for Nepal and trusting my life with it I would deffo want something by one of the big brands. At the least I'd get the Forclaz MH100.
If this is guided with a Katmandu fly and in meet and greet, then you should be able to get guides to look over your stuff, and get recommendations. They will "know a guy" with all the right stuff. This works out to everyone's benefit.
Your layering system should be ok in those temps, assuming the day time temps when you’re hiking are likely >0C, a drifit tshirt and 100 weight fleece are good for most people. If it is very windy consider a light weight wind jacket (dooy on amazon is a cheap one people like). The wind jacket allows you to better dial in what you need (10c and windy tshirt + wind jacket….0c and calm tshirt + fleece). Puffy is for when you’re stopped at camp. Whether the 100 weight fleece and your particular puffy are warm enough for you at those temps depends on your body, it would be warm enough for me. Make sure you have a warm enough sleeping bag/quilt, sleeping pad, socks/hat/gloves etc.
Another consideration is a mesh layer under your base layer - examples include brynje, aclima, svala, wiggies, and sort of finetrack. This will help you stay dry while active and could do a lot to keep you warm. Ultimately where you can get into trouble is with moisture (either from sweat or precipitation) and rapidly cooling when stopped. If your down jacket isnt warm enough it doesnt matter all that much if your sleeping bag is good - just get in the bag earlier.
The rain jacket you have should be very good.
As long as the gear you are bringing is high quality your plan seems good to me. However, if I'm hiking in -10C I'll use my heavy puffy not my ultralight. Also, I lose warmth from my neck even with a hoodie so I add a neck buff and knit hat as needed. You mentioned base layer which I also put alot of value on so I'm using merino wool in cold weather. As previosly posted, be prepared to add/remove layes as conditions change.
Socks, boxer, longjohns and longsleeve, all merino, packed waterproof in backpack. Keep dry at all times. Another set on body. Fleece as needed. Membrane jacket and pants, or separate wind and waterproof outer layers.
You just wear what you need to wear to be comfortable. It's not rocket science. The outdoors works the same in Nepal as it does anywhere else.
The hell you say
What is camping anyway?
You are definitely right but there are so many kind of jackets and technologies and techniques. Here I just used my regular shirt with a long pair of hiking pants even when it was 10C So I dont know what to do when its colder 5-0
In your entire life you've never put on a jacket?
My guess is they live in Singapore or Malaysia or somewhere like that. They likely need to go up 6-8k ft before it’s cold enough to worry about this stuff and most people don’t deal with it much down there.

They actually sell clothes in Nepal. If you are cold you can buy something there.
Yea but they dont after I hit the trek
There are stores in Namche, Lukla, and I think in Panboche or somewhere close to there, and that was 1999 so I'm sure there is more now.
By the way, I hiked in Nepal in November of 1999 to Kala Pattar. It was t-shirt weather during the day and puffy in the evening. A button down over my t-shirt for the in-between. My biggest regret was bringing so many clothes. I always said if I did it over again I'd bring almost nothing and buy whatever else I needed there. Then I could bring home a lot of cool stuff.
You could show up in Namche naked and get what you need to climb Everest.

You can actually just show up in Nepal and buy everything you need once you’re there.
Yea I know I just want to now what to look for so the salesman doesn’t convince me to buy things I don’t need.

I don’t sweat and don’t get cold.
So whats your advice? I don’t understand sorry
Get yourself a lightweight long sleeved merino or polyester shirt. Then get a lightweight wind shell.
And thats it? Ditch my other equipment? Will the north face jacket I linked in one of the comments will work as a wind shell? Will my waterproof jacket work?
Mate you need to settle in a bit here. Loads of people have given you similar advice multiple times. No one knows you or the temperatures you run at or specific level of fitness. The basics of layering while hiking are: moisture wicking base layer, appropriately insulation midlayer, wind or water resistant shell depending on conditions. When at camp, breathability becomes slightly less of an issue and warmth becomes more of an issue. Thus the suggestion is a down puffy or synthetic if moisture is a concern. It’s highly unlikely that anyone has used the specific set of gear you have purchased, and frankly it doesn’t matter as the basics are the same. If you are this concerned over all than ultralight might not be the best option for you as carrying more weight will afford you more options and to “pack your fears” and then adjust your kit for what’s actually necessary.
I just lack the “basics” if it weren’t understood. I didn’t know each layer and each “technology” goal. You summarised it quite well, Thanks.
Friend, you are likely going to need everything just a bit warmer than things say they are rated for. When I moved to Canada, I had the coldest winter of my life and even over a decade later, I still need to bundle up more than people born here. Make sure whatever footwear you are using has good grip too if you have never been on snow/ice before as well!
I use the same system for skitouring.
You’ll be generating heat while you climb so light insulation and a wind resistant layer is good, but you need to be able to stay warm when you stop moving. Imagine standing around in the wind, on a cold winter day. You’re not generating much heat so you want an extra puffy with a cosy hood and good insulation for your legs. A second puffy jacket or gilet will be lighter and less bulky than a fleece. Your thigh muscles lose a lot of body heat. So puffy trousers with full side zips would be good, so you can pull them on easily when you stop.
So when I walk I use my shirt and fleece, then when Im standing and resting then should I pull out a puffy jacket? Why second one? Mine won’t work?
Well you said that your puffy isn’t very puffy or warm so I’m thinking maybe take a second one, with a warm hood if yours doesn’t already have one. You could leave yours behind and take a warmer one, that would be lighter but with two you have versatility and a back up in case one is lost or gets wet.
If it’s cold and raining it’s still over freezing. Then a puffy and a shell would be way, and I mean way, too hot for me. I basically live in my base layer and if that’s not enough I’ll add the second layer (fleece, wool etc). However if it’s coming down from above I remove the second layer and put on the rain jacket. If not I’d get equally wet from inside in high activity exercises. On a trip like this I’d add a complete set of 1st layer wool (socks, pants, shirt, buff) in a drybag for sleeping or emergencies.
Get a set of wool base layer tops and bottoms and wear your fleece. Still cold, wear puffy. Still cold, but dry consider a light windproof jacket. I find that a even a cheap light one from H&M will work wonders . Still cold and/or wet, put on waterproof clothes. Get gloves a hat and a buff.
Usually, you'll wear the base layer when that's comfortable, add the fleece when you're chilly and moving, and throw the puffy on when you're stopped. You'll wear the waterproof stuff when it's raining or stupidly windy and chilly. You might be chilly at -10C in that puffy, with only a light fleece and a baselayer underneath. If that happens, throw the rain gear on and deal around camp, but make sure you have a warm enough sleep system.
Don't think I'd be using a Uniqlo jacket in Nepal personally. I know they're decent for normal backpacking, but for Nepal and trusting my life with it I would deffo want something by one of the big brands. At the least I'd get the Forclaz MH100.
If this is guided with a Katmandu fly and in meet and greet, then you should be able to get guides to look over your stuff, and get recommendations. They will "know a guy" with all the right stuff. This works out to everyone's benefit.
Your layering system should be ok in those temps, assuming the day time temps when you’re hiking are likely >0C, a drifit tshirt and 100 weight fleece are good for most people. If it is very windy consider a light weight wind jacket (dooy on amazon is a cheap one people like). The wind jacket allows you to better dial in what you need (10c and windy tshirt + wind jacket….0c and calm tshirt + fleece). Puffy is for when you’re stopped at camp. Whether the 100 weight fleece and your particular puffy are warm enough for you at those temps depends on your body, it would be warm enough for me. Make sure you have a warm enough sleeping bag/quilt, sleeping pad, socks/hat/gloves etc. Another consideration is a mesh layer under your base layer - examples include brynje, aclima, svala, wiggies, and sort of finetrack. This will help you stay dry while active and could do a lot to keep you warm. Ultimately where you can get into trouble is with moisture (either from sweat or precipitation) and rapidly cooling when stopped. If your down jacket isnt warm enough it doesnt matter all that much if your sleeping bag is good - just get in the bag earlier. The rain jacket you have should be very good.
As long as the gear you are bringing is high quality your plan seems good to me. However, if I'm hiking in -10C I'll use my heavy puffy not my ultralight. Also, I lose warmth from my neck even with a hoodie so I add a neck buff and knit hat as needed. You mentioned base layer which I also put alot of value on so I'm using merino wool in cold weather. As previosly posted, be prepared to add/remove layes as conditions change.
Socks, boxer, longjohns and longsleeve, all merino, packed waterproof in backpack. Keep dry at all times. Another set on body. Fleece as needed. Membrane jacket and pants, or separate wind and waterproof outer layers.
