Review: Great quality, large space. - This is a lot bigger than I thought it was going to be. I really like how much I can fit and then strap down tightly. I took it camping and it rained 3 out of 4 days, so this was perfect. I plan on taking it kayamping too, it's a perfect wet bag for large items. It's a little heavier than I'd anticipated, but quality heavy duty material. I bought this specifically because of the backpack straps and they did not disappoint. I'm thinking about getting another one for my husband.
Review: Good for weekend Scout trips - My son uses this for weekend Scout trips. It fits most of his gear and clothes (the exception is the bulky winter weather sleeping bag) and is waterproof so he can throw it in the back of a pickup truck and not worry. It’s kind of heavy but is sturdy. The orange color helps identify that it’s his and allows him to find stuff in the bottom when it is dark compared to a black duffle bag. The backpack straps are really helpful.

### ⭐⭐⭐⭐ Great Quality!

The bag is nice and has good quality but it is too big for what I need. Will be returning and buying a different size.
