Built for comfort and functionality, the Columbia Rime II Technical Daypack can take you from town chores to wilderness trails and back again. Made from lightweight polyester, this 31 liter pack is treated with Omni-Shield to resist rain and stains. A Backdraft padded back panel and ergonomic shoulder harness offer comfort and support for carrying a heavy load and are designed to move air to keep you cool. When you're hiking in warm weather, dual mesh side pockets on this Columbia backpack keep your water bottles handy while 2 zippered compartments keep your gear organized. Midweek you can carry your laptop or iPad in the padded internal sleeve and be visible on your bike commute home thanks to reflective details.
