This Bass Pro Shops Extreme Boat Bag has a waterproof bottom and is 18" x 10" x 10".

 - Heavy-duty and water-resistant shell

 - Deck-Tuff™ molded bottom

 - EVA foam side-handles with neoprene knuckle guards

 - Easy-to-grip zippers with rubber bumpers

 - Four D-rings for keys, sunglasses, pliers, etc. (there is some rust on some of the D-rings, shown in pictures)

 - 2 side pockets on the inside

 - Zippered mesh pocket inside the top

If there was a removable shoulder strap it was removed one too many times and may have floated away.

In excellent used condition, there are a couple of light marks that I couldn't clean off and there is some rust on the D-rings, see pictures for details. Feel free to let me know if you have any questions.
