When used correctly this bag will keep your rope clean and kink free. Constructed of 1000 denier Cordura nylon with fully padded shoulder straps. The front panel zips open clam-shell style, allowing easy access to the interior. The huge 4'x5' tarp can be removed with the snap of two buckles, creating a perfect day/bouldering pack. The main zipper is the super sturdy #10 YKK. Also features a handy zippered stash pocket inside. Plenty of room for a 60M rope and a bit of gear or two supple 50M's.
