Arkel Dolphin 32 Roll Top Front Or Rear Panniers: Our Dolphins are the most functional, durable, waterproof dry-bags on the market. The Dolphin 32 is the smaller version of the Dolphin 48, but with the same eye to quality and function - a toploader with sewn and taped seam technology that offers an Interloc® System that creates a watertight seal by folding the closures one over the other. Then it's roll, clip and go. An open access storage pouch that features small laser cut holes at the bottom for drainage - eliminating need to store wet items inside the bag, doing away with water build up and condensation. Superior accessibility and the best in dry-bag technology has finally arrived.
