20L For Ooutdoor Sports Clear Window Ocean Pack Waterproof Dry Bag
The waterproof dry bag is good for storing your dry gears when the outside is wet. It is made from heavy duty and durable PVC  MESH material and produced with RWS system (Radiofrequency Welding Seam) that electronically weld the material at molecular level into a seam that is strong and waterproof. The Roll Down Lock with a piece of dark PE strip increase the effectiveness of the waterproof seal. This is done by simply squeezing out the trapped air and folding 3 times and buckle up.
