The KAVU Rope Sling Bag fits the body as a bag should. It's similar in size and design to its fraternal twin the KAVU Rope Bag with one exception: the Rope Sling is made of polyester, making it water-resistant. It also has an ultra-comfortable adjustable rope shoulder strap, two vertical zip compartments, two key or cell phone pockets, and a padded back with KAVU embroidery.
