1. $80. Ultralight backpack! 28 liters, 1 lb 10 oz, 1710 cubic inches, ripstop nylon/ silicone impregnated ripstop nylon; frameless with removable high density foam back sheet. This is a great super lightweight backpack that is no longer available. I adapted it for ice climbing, pretty much carries everything; it was great, one very small hole and a mark from use, other than that it's in good condition. Includes shipping. Originally $119.
