Review on Skog Å Kust BackSåk Waterproof Floating Backpack with External Zippered Pocket, Available in 25L & 35L Sizes by Matt Kucrud

Fantastic bag. I've taken mine (light yellow, gorgeous!) to Mexico and Costa Rica to use on the beach, jungle, and other wet places where I need to carry cameras, clothes, phones, etc. Unmistakably it's a BIG bag to hold a lot of stuff BUT it folds down to a more compact size by folding the top down and then tightening the side straps. This makes it larger than the average backpack. Everything about it seems very well made, from the straps to the zippers to the material. When traveling, it can be folded as it has no inner frame. This makes it easy to store things at the bottom of a large suitcase. Overall a great bag!
