Stone Glacier Helio Zip-Off Mid Layer Bottoms

Stone Glacier’s cold weather mid-layer bottom just got even better with full-leg zips and a velcro waist closure that allow an easy on/off in the field without taking off your pants or boots. The side zips are also placed front-forward to eliminate hot spots under pants and a pack, and the bottom still integrates with all Stratum Layered Zipper System pants in the SG line to allow instant ventilation from skin to shell. And best of all, a new zippered fly makes it a breeze to take a whiz. The Stratum Layered Zipper System is an innovative feature found on all Stone Glacier pants and bottoms. This unique system allows the wearer to vent their layers all the way to the skin for unprecedented temperature regulation without requiring the repetitive addition and removal of layers throughout the day. Increase warmth by keeping all the zippers closed during extended glassing sessions and unzip to quickly ventilate and dump heat during periods of high exertion. No matter the situation, the Stratum Layered Zipper System makes temperature regulation easier than ever. These bottoms are ideal for hiking, camping, skiing, or any outdoor activity where lightweight and breathable insulation is a must.
