CamelBak Zoid Hydration Pack

The Zoid does one thing, and it does it well: it maximizes your time on the mountain without bulking up your ride. The Zoid stows 2 liters of water in a minimal pack that's slim enough to wear over or under your jacket. The Therminator harness features an insulated drink tube that zips away into the shoulder strap, where it's out of your way and protected from cold weather, and the Snowshed back panel keeps powder from collecting on your pack. Two small pockets store the very basics: snacks, phone and keys.
