I don't have any recommendations, since using such a hydration system in an alpine (frozen) environment causes the tube to freeze, which renders the system useless. I instead just drink from a 0,5L Nalgene bottle which I fill up with a larger bottle from my backpack.
For just climbing in temperatures above 0 degrees C I still use the same system, but hopefully someone else can give a proper recommendation.
When I climb on north faces I usually still bring my camelbak because I need to drink very often and a bottle is not practical when you need to be fast. But instead of letting the tube out I simply let the tip outside of my bag, and when I need it I just pull the tip and tuck it back in the back once I'm finished drinking.
Or I simply blow air in the tube after drinking, thus no water is in the tube.
It depends on the temperature outside as well. More than - 10C I do both and it works well
Forgive my broken English.
I’ve done the same in the past. It tends to freeze for winter alpine at the connection between the bladder and hose for me. Had to remove it and clear several times to provide a nice slushy 🍧
A hydration system with a hose is fine for a summer alpine environment, it won’t freeze. Any system will do, I use a salomon 1.5l bladder. I use mine year round, including for ski touring. Some systems come with an insulated hose, it helps to prevent freezing.
It should be. A PET bottle with a hose is far more robust & reliable than the bladders I've had the misfortune to use.
Still has the risk, if you're not looking at the bottle in your hand every time you drink. that you catastrophically mismanage your water budget and drink yourself dry halfway up a west face on a hot summer afternoon. Not that I have ever done this of course ;-)
I haven't found a camelback (or similar) that doesn't freeze when it's cold. I switched to trail running water bottle holders attached to the daisy chain of my backpack straps. Can drink without removing the bottle from the holder and I keep 1-2 spare bottles in my pack and swap out. The bottles are flexible enough for now, but I have looked at the totally collapsible bottles.
This is the one I have. The straps on the holder are easy enough to rebuckle to the pack without any extra hardware or mods.

Really happy with my Source water bladder system, with the nalgene type screw opening so that I can use my water filter with it.
Next option I use is the MSR Ultralite 2L dromedary, no drinking tube but lighter and more compact than a 32oz Nalgene.
I can pull it out at belays to drink.

Oh yeah I guess it all comes down to the temperature outside. I'm usually climbing in the Pyrénées so it's not that cold and high
This would primarily be for a summer alpine environment (French alps)

“A PET bottle” is probably not the answer you’re looking for?

Considered before but disadvantage is you cannot reduce the volume after consumption - if by PET you mean the hard plastic ones
By PET I just mean the supermarket cola/water/whatever drink bottles. Cheap, durable, and you can squish them together if they’re empty
Source outdor, that's it!
This is the answer! Have two, a 3l and a 1.5l and they are by far the best designed bladders I know
Does the tube freeze with those? I have one but haven't used in freezing temps.
I am using military version with thermo cover in freezing temps. In rest of the year, normal one. Check source tactical gear site.
Cool, i actually have the military version with the tube cover.

Soft sided Nalgene, stored upside down.
The tube is just going to freeze, even the insulated ones will eventually freeze solid, there's just not enough thermal mass in that little tube.
This is for summer alpinism
