Insulated stainless steel bottles for cold days on the mountain. Fast flow with gloves on, sized for a pack or a jacket pocket, and no plastic taste at altitude.
Altitude dries you out faster than sea level, cold air holds less moisture, and you're working hard under several layers without noticing you're sweating.
Then the cold suppresses your thirst, so you don't drink. Most people come off the mountain considerably down and put the headache down to the altitude or the wine.
A bottle in the pack that opens easily is most of the fix.
Every insulated bottle marketed at skiers glosses over this, so here's the straight version.
Double wall vacuum insulation keeps the water inside from freezing for hours. The nozzle is a different matter, because it holds a small amount of liquid in a thin channel exposed to the air. In genuinely cold conditions, any bottle with a drinking spout can ice up there. Hydration bladders are worse, because the whole hose is exposed.
Two things help, and they're what we'd tell a friend. Blow the last bit of water back down the nozzle before you close it, so there's nothing sitting in the channel. And carry it inside your pack rather than strapped to the outside, where a jacket and your own body heat do most of the work.
Do that and you'll drink all day. The bottle isn't the problem, the last teaspoon in the spout is.
Unscrewing a lid in ski gloves means taking a glove off, which means putting a pole down, which means you don't bother.
Our nozzle flows on gravity and opens with a flip. Pop it, tilt, drink, close it. Developed with an ex-NASA engineer, it moves 621ml in 8.5 seconds and needs no squeezing, which is just as well in a bottle you can't squeeze anyway.
The silicone anti-slip exterior on the coloured bottles grips through gloves rather than sliding out of them.
The Trio Mini is 500ml and 220mm tall, which fits a small avalanche pack or a day pack without eating the space you need for a shovel, layers and lunch. It'll go in a large jacket pocket too, which is where it stays warmest.
The full size Trio at 621ml is the one for touring days and longer descents where refills aren't happening.
Touring is where hydration actually bites. You're climbing for hours under load, sweating hard in cold air, and there's nothing to buy at the top.
The Trio Mini earns its place in a touring pack on weight and volume, and steel means it survives being packed against skins, a shovel and a set of edges without splitting.

Double wall vacuum insulation keeps the water itself from freezing for hours in typical ski conditions. The nozzle can ice up in real cold, which is true of any bottle with a spout. Blowing the last of the water back down the nozzle before closing it, and carrying the bottle inside your pack, largely solves it.
The 500ml Trio Mini suits a resort day with lunch stops. For touring or long days without refills, the 621ml Trio.
For cold weather, generally yes. A bladder hose is fully exposed and freezes readily, whereas a bottle inside a pack stays protected and you can clean it properly.
Yes. There's no lid to unscrew, so you flip the nozzle and tilt. The silicone exterior gives grip through gloves.
The Trio Mini at 220mm tall fits most large jacket pockets, which is also the warmest place to carry it.
Steel takes knocks that split plastic. It may mark, and the raw stainless finish wears that well.
Riding or running through winter too? We build for both, alongside the full range of stainless steel sports water bottles.
