The ultimate "utility" daypack, the Avail 2200 is built to carry any essential gear for backcountry adventure. The Avail 2200 is designed to be used either stand-alone with its own Avail suspension and internal frame, or you can remove the shoulder straps, hip belt, and frame to mount the Avail directly to the Xcurve Frame or EVO Frame for heavy load-hauling capability. Because it uses the same shoulder straps as theexternal frame, the Avail can be quickly swapped from external frame mode to daypack stand-alone mode in the field.
