Stone Glacier Helio Zip-Off Bottoms Fern XX Large – Breathable Cold-Weather Layer

Meet the Stone Glacier Helio Zip-Off Bottoms in Fern, a mid layer engineered for late season hunts and damp, cold mornings. Weighing just 10.2 oz in size large, these bottoms deliver warmth through a highly breathable microgrid fleece that traps heat without overheating, helping you stay comfortable as you hike, glass, or stalk.

Designed with the Stratum Layered Zipper System, they feature full leg zips for rapid on off over boots or under layers, and side zippers placed to minimize hot spots when worn under other pants or a pack belt. A zippered fly adds convenience for quick breaks without removing layers. The waist fastener is a Velcro closure that gives you a snug fit in the field, plus adjustability for layered transitions.

Materials and tech also promote odor control and durability. Premium YKK zippers withstand the rigors of field use, and Polygiene odor control helps maintain freshness during long days. The lightweight build allows you to compress into a pack without bulk while staying ready for movement in varied terrain.

Versatility is a core strength. Wear these bottoms as a stand alone mid layer on chilly mornings or pair them with the M7 Pant or the Stratum Layered Zipper System for a modular, adaptable system. The strategic side zipper placement reduces hot spots when layering under pants or carrying gear on long approaches, while the Zip-Off design converts into shorts for late sun breaks or warm spells at midday.

Real-world scenarios where these shine include backcountry hunts with long approaches, early morning sweeps, or post-hunt camp transitions. The Fern color blends with terrain while the fabric maintains comfort under a pack hip belt, keeping bulk down and mobility high. The combined features deliver a balanced experience of warmth, breathability, and field-ready practicality, without making promises beyond what the product supports.
