I have several of these in different sizes. Getting ready to order one more. Much easier to access contents. Rectangular shape packs better. Been using them since they came out. Only one caveat: They are not waterproof. The seams will leak (can be sealed with silicone) and the zippers are water resistant, but not water proof. If they get dunked, you'll be OK, but leave hang your food bag out in the rain all night and the contents will get wet (ask me how I know). I line my food sack and my clothing sack with a turkey bag and problem is solved. I've replaced all my sacks with this style, except for my sleeping bag which always goes in a waterproof sack. Highly recommended in spite of note being waterproof.
