The Rope Sling in Motion Undertow from Kavu.

The Rope Sling is designed to hug your body like a bag should, just like its fraternal twin the KAVU Rope Bag. The only difference? This one is made of water-resistant polyester. It features a super comfy adjustable rope shoulder strap with a side release buckle, two vertical zip compartments, two pockets for your keys and phone, and a padded back with cute KAVU embroidery. Oh, and it comes in an array of colors and patterns - so go ahead and let your personality shine!
