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.
