UPGRADE: matching storage roll-top tarp bag

Additional upgrade to the CLASSIC, HEX & WHELEN(ish) tarps.

Made-to-size roll-top bag, using the same fabric, leather and rivets as your tarp. This will fit your tarp to keep the muck out when stuffing it in your pack, or works as a matching storage bag to keep your kit cohesive. Roll tops work well as dry-bags, this isn't watertight but will survive an accidental dunk better than most
