When winter hits hard, the HyperDown Pant is built to keep big-game hunters in the field. Designed to wear over your existing layers, this ultra-warm insulated overpant delivers serious cold-weather protection with the packability and durability needed for demanding hunts.
Built for hunters who take winter weather in stride, the HyperDown Pant is the warmest puffer pant in the line. It is insulated with 220 grams of 800 fill power PrimaLoft® Gold down blend with Cross Core Technology, using a 90% down / 10% synthetic blend for exceptional warmth. You also get the packable, compression-resistant performance of synthetic insulation, making it easier to stow, carry, and deploy when conditions turn brutal.
The 27D ripstop polyester face and 10D ripstop nylon lining help resist snags and tears in rough country, while the 27D ripstop face fabric is doubled on the seat and knees for added toughness in key wear zones. And when it is time to layer up fast, 7/8-length easy-access side zips make on-and-off simple, even over boots.
