The KLIM Keweenaw Jacket is built for riders who refuse to let brutal cold cut a ride short and somehow still think "another hundred miles" sounds reasonable at negative twenty. Designed specifically for extreme cold-weather trail riding, the Keweenaw combines premium insulation, elite waterproof protection, and long-distance comfort for serious northern winter conditions. Built with a rugged GORE-TEX Performance Shell and loaded with heavy 3M™ Thinsulate™ insulation, this jacket delivers exceptional warmth without sacrificing mobility or durability. Full pit vents and a large rear exhaust vent help regulate airflow during changing conditions while the articulated trail-riding fit improves comfort during long days in the saddle. Warm, durable, and purpose-built for brutal winter riding, the Keweenaw Jacket is basically designed for riders who see frostbite warnings and still start checking trail reports anyway.
