What Our Gearhead(R) Experts Are Saying:"This jacket lives in my running vest and hiking pack-it's light, it blocks wind and light drizzle, and it packs into its own pocket. I especially like the back venting; it dumps heat without letting the wind cut through. It's a great just-in-case layer that ends up being essential more often than not."On blustery ridgelines, early trail starts, or exposed approaches, we count on the Columbia Trailborne Jacket to block wind and stay breathable when we're moving fast. Built with Omni-SHIELD(TM) advanced repellency, it resists light moisture and wind while maintaining an ultralight, packable design that disappears into our pack when not in use. The stow-away hood provides extra coverage when needed, and the back venting system prevents us from overheating on the climb. Zippered hand pockets secure our small essentials, while reflective detailing keeps us visible when we're chasing daylight. Simple, effective, and dependable, it's the kind of layer that earns permanent pack space.
