The Bison Zip-Up Jacket is a lightweight, weather-resistant layer fitted with a high collar, side pockets, and short length. Its exterior is crafted from 100% recycled polyester that keeps plastic waste out of landfills, while its interior is filled with our signature BisonShield™ insulation – a temperature-regulating material made with salvaged bison wool that we intercept from the waste stream. This responsibly-made piece is part of The United By Blue Impact Collection: an intentionally-designed capsule of sustainable goods at accessible price points – allowing us to reach more people and clean more trash than ever before. 1 product purchased = 1 pound of trash cleaned.
