Dry, lightweight sack
It is what it is, a good, very lightweight, and compact dry bag. I've used it to hang food when backpacking in areas that allow hanging food. It packs down super small, which is why I was so interested to begin with. Seems pretty sturdy, I've thrown it around camp on various terrain and held probably about 5-10 lbs of stuff when hanging from the tree without issues. I haven't filled it with knives and sticks, but it hasn't been pierced yet. I have not heavily tested the waterproofing, but it has rubbed up against water containers with a lot of condensation and sat out overnight with heavy dew on it and there were no issues with dampness inside. I don't think it will, but if this bag fails, I'd probably buy it again for the price.

Superlight, but not super cheap
In the category of "you get what you pay for," I am hoping that these stand the test of time. They are very light, and seem a bit thicker/more durable than some others that I have purchased. But make no mistake, they are still very light! The one issue I have - and I would have deducted 1/2 a star but I can't do that - is that the rigid strip that is part of the roll top closure is folded when you get it. I think this is for packaging purposes, but it seems to be unfixable - in other words, you can't "fold it back" to be totally straight. I don't think this affects the quality, usability, or waterproofness of the sacks, but it is a little odd. There must be another way to roll the bags for packing/shipping/selling that doesn't involve bending the strip in 1/2? Again, not a functional issue, but kind of a cosmetic issue, but kind of a logistics issue...I would still consider buying again, but they certainly are not cheap!

Keeps my items dry on the boat!
I bought this to keep my personal items dry while on a scuba diving boat. This works really well and is a great size for me to fit my things! The only downside is if I don’t bring a bag to put this in, it can become a bit cumbersome to carry on its own. I bought this knowing it didn’t have backpack straps so I can’t knock this product for being exactly what it is advertised to be - thus still 5 stars. I’ve attached a carabiner to help with carrying, and it is great stashed in a tote bag or backpack.

Rolls up incredibly small, lightweight, and durable. I've only used it once, but seems like it will hold up.

6L is what you need!
The color, size, and mouth of the bag to keep things sealed are perfect! The reason why I'm not giving it 5 stars is because I'm a little nervous about the material and possibly getting a hole--it seems very thin, but I'll baby it as much as possible since the color is unbeatable! For reference I put a towel inside, 6oz sunscreen and my glasses. These are normally my essentials when I go paddleboarding, snorkeling and rafting. I attached a small carabiner clip in case I need it to hook to something.
