SITKA’s HyperDown Collection redefines warmth and resilience for extreme conditions, blending the insulating benefits of down with the wet-weather performance of synthetic fibers. Tested in punishing environments like the Canadian Rockies and Alaskan Chugach Range, this collection features the HyperDown Jacket and Pant, both insulated with an 800-fill PrimaLoft® Gold down blend. The jacket, with its 27D ripstop shell and ergonomic cut for layering, packs down light yet delivers warmth in harsh, late-season hunts. Similarly, the HyperDown Pant, designed to pull on easily over other layers, features reinforced fabric at the seat and knees for rugged use. Both pieces are optimized for quick layering with 7/8-length zips on the pants and ample pockets on the jacket. Available in three colors, the HyperDown Collection provides serious hunters with a reliable defense against extreme weather, keeping focus on the pursuit rather than the conditions.
