Inspired by climbing, then refined to expand its versatility, the Gamma LT Jacket works on rock, trail, and easily transitions to daily use. Made from a light, durable double weave, it blends wind and water resistance with breathable comfort. The clean, athletic fit allows room for light layers, and performance stretch gives you freedom to move. Born in British Columbia where the mountains meet the sea, this is a proven performer built to handle a range of conditions and landscapes.
