The Granite Gear Nimbus Ozone Backpack is a full-suspension, fully framed pack that weighs a mere three pounds. The Nimbus Ozone allows you to carry 40-pound loads in amazing comfort, thanks to a 3D molded composite Topoflex frame and an ergonomically designed harness system. Are you the backpacker who has made a conscious decision to reduce your pack weight, but you still like shelter? Do you still want to cook up some gourmet cuisine and maybe have a couple shots of your favorite libation at the end of a long day? If 35 to 40 pounds just seems to be as light as you can get, this is your pack.
