Excellent Design & Quality, but Pricey
The heading pretty much says it all. Very good quality well-suited for rugged use and longevity. The oval shape is very useful for fitting a 13L bag into round kayak hatches which was the case in my situation. I like that the material is nylon and not rubber as with other heavy duty bags. This allows for easy sliding in and out of tight spaces such as in a kayak. The rubber bags are a real pain to wedge in and out of a kayak.
I purchased this bag at a 25% discount and still thought it was very expensive for what it is.
