Founded by local climbers in 1989, Arc’teryx remains the go-to for innovative and purposeful outdoor design. The Nuclei FL jacket is inspired by athletes, and its ergonomic build provides unmatched shelter from the harshest alpine conditions. This next-generation version is lighter than the original, without sacrificing on warmth, so you can move quickly on your climb whilst staying protected with Coreloft™ insulation and a StormHood™.
