Epperson Mountaineering’s Packable Backpack is the lightest backpack to date, it is so light you might forget you are wearing it. Constructed with durable nylon ripstop that resists tears. The bag is finished all around with clean binding and reinforced with bar-tacks. Features drawstring closures, heavy duty zipper, and climbing-spec ‘daisy chain’ webbing (a chain of small loops reinforced with bar tacks) for increased utility and durability. The backpack can be folded up and packed into the top zipper pocket for easy storage.
