Lightweight Warmth When Conditions Demand More
When temperatures drop, the right insulation layer can make all the difference. The BE:1 Reactor Puffy Pant is built to deliver packable, low-bulk warmth that keeps you comfortable during cold sits, long walks, and unpredictable conditions without sacrificing mobility or adding unnecessary weight.
Powered by 60g Sorona® Aura insulation, the Reactor Puffy Pant delivers exceptional warmth for its weight, keeping you comfortable in colder conditions while maintaining a streamlined fit. Unlike bulky insulated pants that restrict movement, the Reactor is designed as a versatile layering piece that moves with you and packs down easily when not in use.
The durable nylon woven ripstop shell stands up to the demands of the hunt, while a soft peached lining adds next-to-skin comfort. A DWR treatment helps shed light moisture and resist stains, ensuring the Reactor performs when conditions become less than ideal.
Built for hunters who demand stealth, the Reactor Puffy Pant incorporates Carbon Alloy® technology to adsorb odors and help keep you undetected in the field. Whether you're layering beneath your outerwear for a late-season sit or adding warmth on a cold morning hike, the Reactor helps maintain your concealment while maximizing comfort.
Practical field features include an elastic waistband with an adjustable internal drawcord, two secure invisible zipper waist pockets, and a center-front fly zipper for convenience. An 18-inch side seam zipper allows for quick and easy on/off over base layers or hunting boots, while rib knit lower leg cuffs help seal in warmth and maintain a secure fit.
Designed to be packed, layered, and deployed whenever temperatures demand it, the BE:1 Reactor Puffy Pant delivers the warmth, mobility, and scent control serious hunters need throughout the season.
Packable. Lightweight. Ready when you need it most.
