Coulee is a deep ravine carved by water. It also means flow, the perfect terminology surrounding this adventuresome little day cooler. Built for side trips and short quests, but make no mistake, it still works like a mule. The wide mouth roll top opening and thinner insulation profile allow easy loading. The side air valve allows for extra flotation or more cushioning. That's right, it even floats!The perfect companion for bicycling the Rockies, dropping into Sedona's creeks. The premium cushioned straps and padding keep you happy, and the lightweight keeps you moving at your pace. Includes a handy front pouch for extras like cell phones, keys, or your favorite pocket carry items. Fully welded, nontoxic premium liner keeps food safe and stops the soak.
