Reinforced clear mesh expedition grade roll top dry bags
Carry strap provided with nylon swivel clips at each end. The D ring attachment can be used as a tie point to attach the drybag to your boat
To roll - fill the bag half way with kit. Squash the bag to remove excess air and start rolling the top tightly four times to create a watertight collar then clip together.
Construction looks very good, and it rolls down small no problem. I really like it
