Industry-leading innovation you’ve come to expect from Stone Glacier. Now, in a clothing system specialized for mountain hunters.

Moving Forward

When we created the first Stone Glacier pack, the goal was simple: create an ultralight, durable, functional hunting pack that can instantly transition from the hunt to the packout. We then set out to create Stone Glacier products that would replace everything else we used in the field. A decade later, we offer complete gear systems for the hunter — from packs to apparel, gear, shelters, and sleeping systems — but the ethos remains the same: redefine the capabilities of ultralight gear for the hunter.

We are proud to bring this same approach to our apparel line, and we’re confident every product will rise to the occasion of your hunt.

See you on the mountain.

New Layers

Active Insulation

Active insulation utilizes highly breathable, quick-drying technical fabrics for use as outer layers during lower activity in cool temps, during heavy exertion in cold conditions, or as insulation under a shell in wet weather. These innovative layers keep the wearer dry and thermally regulated, reducing the need to shed or add layers throughout a hunt.



Our cold weather mid-layer bottom features full-leg zips and an innovative velcro waist closure to 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.

durable protection + packability

Built with our proprietary waterproof textile technology, HydraShield™, the M5 is constructed with a mechanical stretch 3-layer laminate that boasts a waterproof rating of 31,000 millimeters and a MVTR breathability rating of 27,600g/m2/24hr. A full feature of innovations includes our Patent Pending Contour Waist™ System for ease of layering, YKK Vislon® and Aquaguard zippers, and our unique Stratum™ Zippered Layering System. The M5 Series provides the protection you need from Mother Nature’s elements when deep in the backcountry.

Waterproof + Windproof + Breathable


Proven in unforgiving mountain conditions, HydraShield™ technology excels when Mother Nature is at her worst. Waterproof, windproof and breathable, HydraShield™ textiles are incredibly durable while also remaining lightweight and packable.

HydraShield™ technology prevents rain and snow from passing through to your body while transporting water vapors from sweat to the exterior of the textile during high exertion activities. This transfusion process ensures you stay warm and dry in all wet weather conditions.

We launched our proprietary line of waterproof breathable textiles, HydraShield™, with a 3-Layer textile designed for the ultimate in durability and packability. We then expanded the HydraShield™ line to include HydraShield™ SS, a waterproof breathable soft-shell, and HydraShield™ RS, a rip-stop version for increased durability in high-wear pieces, such as our all new SQ2 Alpine Gaiter.

Packable Insulation


Constructed with industry-leading technologies and best-in-class materials, the Grumman insulation pieces have a better warmth-to-weight ratio than any other down insulation we have ever tested. 850+ fill HyperDry™ waterproof down insulation wrapped in a Pertex® Quantum shell guarantee the Grumman Goose Down Jacket and Pants will keep you warm and comfortable on the coldest backcountry hunts while ensuring the ultimate in ultralight packability.


Insulating Mid-layer

Helio Series

Updated for 2021, our best selling Helio Series now boasts a performance grid fleece textile that insulates and transfers moisture better than ever. Available in a Hoody and Bottoms, the Helio Series incorporates Polygiene® Odor Control Technology and our innovative Stratum™ Layered Zipper System. These are two pieces that should be included in every hunter’s kit.

Chinook Merino Series

The Chinook Series of base layers further builds on our technical apparel line, allowing us to offer a full skin-to-shell system for the backcountry hunter.

Merino6™ is our propriety blend of the highest quality Merino wool and high-performing nylon 6.6 micro denier yarns. After extensive testing, we found the perfect combination to be 89% Merino wool and 11% nylon. By blending wool and nylon, we created a textile that leverages the benefits of Merino with all the advantages of nylon. Merino6™ products have an extremely soft hand feel, regulate your body temperature while eliminating odor, and won't stretch or shrink like traditional 100% Merino textiles. Additionally, the nylon fibers increase the moisture-wicking ability of the garment and enhance the durability of the textile, creating the perfect backcountry, next-to-skin layering piece.


Comfort from the sun


Moisture and odor are no match for the new SG Synthetic Series, which is built with Synthetic Fabric Technology and features Polygiene® odor treatment. This series is made for those long early season days and to be your next-to-skin layer in the late season when moisture and odor management are paramount. With an anatomical fit, supple polyester, and strategically placed shoulder seams to reduce backpack friction, the SG Synthetic Series is a key addition to your layering quiver.

UPF 43+
SG Synthetic tops protect from the harmful effects of the sun, blocking more than 95% of UV rays.
