It's a cold-weather version of a hydration vest, with extra-light, breathable materials and two sternum straps for a secure, bounce-free fit, plus an insulated drink tube to keep your water from freezing in cold temperatures. Plus, the new Crux reservoir delivers 20% more water with every sip, and features an ergonomic design that's easy to grip even with gloves on.

When you're on the mountain, the last thing you want is to be looking for the one piece of gear that fell to the bottom especially when you're wearing gloves. The SnoBlast's tri-zip design lets you choose between opening the top of the pack, or unzipping it down the side to instantly access all of your gear. When you really want to load up, the external attachment points let you strap on additional gear. In addition to our 2L Crux reservoir, the Therminator harness also keeps your insulated drinking tube zipped securely into the shoulder strap, which keeps it from freezing in cold weather so you stay hydrated on even the coldest peaks.
