This bag is HUGE! Seriously, you can fit a ton into this waterproof bag. I bought the Quadratec aluminum carrier as well, and this bag fits it perfectly, and it comes with straps to secure it. The bag is expandable, so when you really need to carry a huge load, you can unzip the bottom and it gives you extra room. The first night I used mine we had some terrible storms, and everything in the bag was totally dry. I would carry anything in this bag with total confidence.
