Lynx StormShield – Weather-Resistant Down Sleeping Bag for Winter

When conditions turn severe and temperatures plummet, the Lynx StormShield is your trusted companion. Purpose-built for extreme cold, this weather-resistant down sleeping bag for winter delivers reliable performance for mountaineering, backcountry ski tours, and deep winter camping. Rated to -10°F and protected by our StormShield™ shell, the Lynx offers outstanding warmth and dependable protection from the elements—without excess weight or bulk.

The StormShield™ shell is a breathable, windproof, and water-resistant microfiber that helps shield the premium 850+ fill power down from moisture while maintaining loft and comfort. Whether you’re camped above treeline or hunkered down in a snowy forest, this shell fabric ensures that external condensation or spindrift won’t compromise your insulation.

Inside, a full down-filled draft collar and insulated draft tube seal in warmth and block cold air from creeping in through the zipper. The Lynx’s ergonomic cut is slightly narrower than our Kodiak, offering a thermally efficient fit that still provides enough room to sleep comfortably with layers or shift positions during the night.

With 32 oz of high-loft goose down, the Lynx packs exceptional warmth into a surprisingly lightweight and compressible form—ideal for expeditions where gear weight matters but failure is not an option. The full-length zipper offers flexibility in venting, while durable construction ensures long-term performance in rugged winter environments.

Whether you’re planning alpine ascents, ski traverses, or snow camping in the depths of winter, the Lynx StormShield is engineered for comfort, protection, and peace of mind in the harshest conditions.

Proudly made in the USA, this bag is for those who dream big, sleep cold, and refuse to compromise on warmth or weather resistance.
