The CSL Dry Holdall is constructed from a transparent waterproof PVC to increase internal visibility - no more hunting around for that all important item. The dry roll closure at the top of the bag ensures a 100% waterproof seal. An air release valve as well as compression straps mean any excess air trapped inside the bag when full can be released to reduce that all important storage space on board a boat. All seams are welded and other features include reinforced grab handles and a padded, detachable shoulder strap.
