Insulation is pretty binary; you either sport a synthetic down jacket, or you have a real duck-down jacket to keep you warm. United By Blue, the sustainable outdoor wear brand based in Philadelphia, is upending that dynamic with their Bison Sport Jacket.
An update on a pre-existing model, this American-made jacket uses a special B100 insulation that’s made up of responsibly sourced Bison fiber and wool to provide loft and keep wearers warm even in the harshest weather. In keeping with their sustainable mission, United By Blue gets this fiber by working with ranchers and tanneries – removing the fiber before hides are sent off to be turned into leather goods. But more than just keeping you warm in a unique and environmentally responsible way, this jacket also boasts a weatherproof build. The shell of the winter layer is constructed from a 2-ply high count Taslan nylon with taped seams and a YKK Aquagaurd zipper that beats back water and the elements at every turn. Have a lot of gear to carry? The Bison Sport Jacket features a bevy of pockets and sleeves for carrying your gear with you. The jacket will be limited to just 1,000 examples, and is guaranteed for life.
