The versatile Gregory Keeler Backpack fills the gap between too-small weekend packs and too-big multi-day packs. With a 4800cu in volume in a size medium, the Keeler can handle everything from four-day weekends to bare-bones weeklong backcountry adventures. It'll carry up to 40lb of gear comfortably thanks to Gregory's Auto-Cant shoulder harness, which adjusts automatically to your specific next and shoulder shape and angles. The Flo-Form II backpanel places soft, cushy foam next to your back, and a denser foam behind that to provide fitting form and support. You can easily get to all your gear through bottom, top, and side access points. Multiple exterior pockets and gear loops help you organize your load, while water-resistant fabrics and zippers keep your gear dry.
