Mystery Ranch put just as many thoughtful details in their day hike-oriented Coulee 20L Backpack as they do in their multi-day packs. Using the micro-adjustable Lightweight Trail yoke and load-adjustable straps, we can find our perfect fit and balance for intense days on the trail and quick excursions to our local swimming hole. One of the most interesting and convenient features of this pack is the 3 ZIP opening: the top opens with a quick-pull two-zipper lid, and an additional zipper down the center of the pack expands the main compartment so we can access contents more easily.
