Every Sumo sac is double welded to ensure a watertight seal. The tough Sumo Skin is overlapped and hot air welded. You can see the smooth and clean seams on the outside of every bag, and a second welding operation applies an inch wide sealing tape to the inside of every seam.

    Recommend as a rear locker bag, not as a floor or seat bag.
    Adam Tabor

    This bag would be better suited as a rear locker bag on a older boat with a smaller rear locker. When full its a little too tall and has a tendency to want to roll over if filled in the middle of the boat. I should have bought the 475 size for my needs.
