Epperson Mountaineering's Packable Parachute Bag is constructed with a Windproof Nylon Ripstop along with a military-grade tubular nylon webbing. In addition, the fabric is extremely light, yet resists tears with great toughness due to its construction. Drawstring closure and climbing-spec daisy chained webbing (a chain of small loops reinforced with bar tacks) along the face of the bag increase utility and round out the unique climbing-meets-military aesthetic.
