The Attwood 40L Dry Bag is large enough to hold all that I need kept dry, though perhaps a bit larger than what I need. Fully loaded, the weight of the bag makes the shoulder strap really uncomfortable. The carry handle becomes convenient for lugging it around at least. The material seems pretty durable, I’m not much concerned with just tossing it in and out of my canoe. There are multiple D-rings which come in handy when I need to strap down the bag.
