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 thats 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 its 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.FEATURES • The brand new Crux Reservoir delivers 20% more water per sip, with an ergonomic handle for easier refilling, and an on/off lever that makes it easy to prevent leaks. • Snowshed Back Panel: Back panel repels snow and keeps it from sticking to your pack • Therminator Harness: Drinking tube zips into an insulated sleeve in the shoulder strap to protect your water supply from the elements • Lift-Friendly Design: Slim, low-profile design lets you wear this pack comfortably on the lift • Secure zippered pocket keeps your smartphone in easy reach • Adjustable sternum strap slides up and down the harness for a custom, chafe-free fit.SPECIFICATIONS COLLECTION: Ski & Snow ACTIVITY: Ski & Snow USER: Unisex HYDRATION CAPACITY: 2L/70 fl oz HYDRATION TYPE: CRUX Reservoir with Quicklink System BPA/BPS/BPF FREE: Yes QUICK LINK DISCONNECT: Yes GEAR CAPACITY: 1L/60 cu in PACK WEIGHT: 290 g/10 oz FITS TORSO: 38-53 cm/15-21 in BACK PANEL: Snowshed: Molded back panel with moisture-wicking DWR finish for snow-shed capability.
