With a women's-specific harness, the Mystery Ranch Coulee 20L Backpack is fully loaded with technical details to help all our day-hike adventures go off without a hitch. The micro-adjustable Lightweight Trail yoke and load-adjustable straps allow us to find our perfect fit with ideal stability to handle undulating terrain. We love the hydration-compatible internal sleeve and tough, eco-friendly construction, but our favorite feature just might be the convenient 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 for hassle-free gear access.
