Big, Small, it Does it All. Meet the versatile pack that hauls it all. The Flex Capacitor 60-75 is a beast of a backpack, constructed from durable nylon for rough conditions in the backwoods or backcountry and built with adjustability in mind. Loosen the expanding horizontal gussets for an additional 15-20 L of cargo capacity on longer backpacking trips, or cinch it tight for smaller, compact loads on fast summit days. Plus, ample quick-stash solutions on the straps, sides and bucket lid ensure there are plenty of places to store your mid-trail essentials. However you pack it, the Y-Flex suspension adds support so this lightweight backpack can hit well above its weight class.
