This bag comes in handy to carry al your weight, both your pockets as your supplementary weights for special conditions (e.g. salt water, different bottles). Due to the holes in the bottom water runs out. Easy to carry, combines perfectly with my Gorilla bag for my diving gear without a fear of crushing my more vulnurable stuff.
One disadvantage: as the water runs out on the bottom site, after the dive when putting back the gear in your car you have to put a towel under it so your car won't get wet. An optional plug for the two holes (as with the Gorilla-bags) would make the bag more than complete!
