There are way better bags on the market. This thing is bulky and belongs at the beach with some old lady with over-size sunglasses.

So after not knowing which size to buy, I finally opted for the 20L and it was much larger than I was expecting. Plenty of room for clothes, towel, food, whatever you would need for a day or maybe even a light over night packing. You won't fit a sleeping bag in there, but clothes and other personal items would fit no problem. I also have a 10L bag which is great for smaller items, food, or a few clothes. I haven't tried to stuff it, but it's great for a day trip. I haven't submerged these under water, but they have gotten wet on the outside and everything inside remained completely dry. I like having the see-thru window too. It's foggy, but easy enough to see what's in there. Great bag for the price.. I wouldn't hesitate to buy more of these.

Good bag for semi-waterproof protection. I use these inside a waterproof case for packing. I picked the 20 L bag to replace several 10 L bags I had before. The window and purge valve help organize. I have yet to put them to major use yet so I can't comment on durability. Made in USA.

The dominate yellow makes retrieval of this dry bag easy when it comes to finding it down river. Its expansive size easily fits an extra pair of clothes as well as other gear, and yet it's compact enough to fit anywhere in the kayak.
