The bag is the NRS Large Purest Duffel. 30" Long x 16" Diameter, 6005 cubic inch volume
Sturdy 600-denier urethane coated polyester fabric forms the bottom and ends. Heavy-duty mesh in the top allows moisture and odors to leave. All the handle stress points backed with webbing on the inside of the bag so they can't pull out. A removable shoulder strap is included. Sturdy 4-foot diameter nylon pad stows in a zippered pocket in the bag when not in use. Standing on the pad while getting into your gear protects your feet and keeps things clean. When you've changed at the end of a wet day, just tug perimeter cord-lock drawstring and your soggy gear is in a neat bundle.
