Black — the only colourway we've taken.

This is the hill one, not the office one. Hydration-compatible, daisy chain loops down the front for clipping gear to, and a rescue whistle built into the sternum strap buckle — the sort of detail you don't think about until you need it. One large main compartment for bulkier kit, an external zipped pocket, a front pocket with hook-and-loop closure, and two bottle pockets alongside the hydration sleeve. Multiple grab handles let you pick it up from any angle. The Omni-Shield 100% polyester shell sheds light rain and resists staining. 47 x 26 x 17cm and only 450g, which is genuinely light for 25 litres. Style UU4050010.

Columbia was founded in Portland, Oregon, in 1938 as the Columbia Hat Company by Paul Lamfrom, taking its name from the river that runs past the city. Gert Boyle took it over in 1970 and her son Tim Boyle has led it since 1988, translating Pacific Northwest weather-testing into outdoor gear built to be worn rather than looked at.

You'll find the full Columbia range at Fat Buddha, more backpacks and bags and the rest of our accessories.
