Packable Warmth. Uncompromising Performance. Temperature swings are inevitable throughout hunting season, but being unprepared doesn't have to be. The BE:1 Reactor Puffy Jacket is designed to deliver on-demand warmth whenever conditions call for it, making it an essential piece in any serious hunter's layering system. At the heart of the Reactor is thermally mapped SoronaA(R) Aura insulation, strategically placed to maximize warmth while minimizing bulk. With 80g insulation in the core and 60g in the arms and hood, the Reactor traps heat where you need it most while maintaining the mobility required for active hunts. The result is a lighter, warmer garment that packs down small and layers effortlessly beneath your outerwear. Built with a durable nylon shell and a smooth, low-profile surface, the Reactor slides easily under jackets and bibs without the friction and bulk often associated with insulated layers. A DWR treatment helps shed light moisture and resist stains, while the soft peached lining enhances comfort during long days in the field. The Reactor doesn't stop at warmth. Featuring Carbon AlloyA(R) technology, it actively adsorbs odors to help keep you undetected when close encounters matter most. An adjustable high-neck hood, articulated elbows, and an adjustable waist work together to seal in warmth, block wind, and provide unrestricted movement in any hunting scenario. Five strategically placed pockets keep essential gear secure and accessible, making the Reactor just as practical as it is versatile. Whether you're facing a cold morning walk-in, a long sit in the stand, or unpredictable weather throughout the season, the BE:1 Reactor Puffy Jacket delivers lightweight warmth, scent control, and packable performance when you need it most.
