Sealock produces this full airtight waist bag. We use the full airtight zipper as the main compartment zipper, so you can place all your items in the bag without worry, because you can safely sink the bag into the water for use. The material can be either plain solid color or camouflage. There are many camouflage styles available. The bottom of this dry surfing waist bag has a quick buckle, which can easily place your coat, towel or wet items. The belt is adjustable, with a mesh bag for placing water bottles. The mesh bag has a retractable rope to fix your water bottle. There is a storage mesh bag in the waterproof SUP waist bag, which is convenient for you to place items by category. Enjoy your SUP with Sealock airtight diving bags.
