Does anyone have any experience using this backpack (https://www.patagonia.com/product/guidewater-submersible-waterproof-backpack-29-liters/49165.html)? We are looking for something to carry camera equipment while on the water. Our preference is for something that can be kept in easy reach rather than stowed away in a hatch. Would appreciate feedback on this item or recommendations for something similar. TIA!
