The Sitka M's HyperDown Jacket is built for ounce-conscious big-game hunters who need maximum warmth without unnecessary bulk. As Sitka's warmest puffer, it combines 800-fill PrimaLoft® Gold down blend insulation with a durable ripstop shell for packable performance in severe cold.
The jacket uses 230 grams of 800-fill PrimaLoft® Gold down blend with Cross Core Technology, combining 90% down and 10% synthetic insulation. This construction helps resist clumping in damp conditions while maintaining loft, warmth, and compressibility in the field.
A 27D ripstop polyester face fabric helps resist snags and tears, while the 10D ripstop nylon lining keeps weight low. The cut is designed to fit over other hunting layers and an optics harness, allowing fast deployment when temperatures drop.
Zippered hand pockets provide secure storage, while two interior mesh dump pockets offer space for gloves, socks, and other small items that need to stay warm. An adjustable brimmed hood, adjustable hem, and elastic cuffs help seal in heat and block cold air.
