I wanted a new dry bag to put some foam into as padding for camera equipment to take on dive boats with me. This is perfect for the job.
Initial reactions were that it was too big, but once you put something in it and roll the top down a few times, it becomes the perfect size. I bought a cheap gym mat and cut it so that it provides internal padding for delicate camera equipment and the clasp means I can hook it to the A frame of a dive boat, to keep it secure. There's another convenient carry handle, which is sturdy and also an optional clip on strap which is useful for carrying it over the shoulder when lugging other things around.
All in all, it's a great bag - sturdy, watertight (importantly!), and just the right size.
Excellent delivery from the seller as well.
