I bought this bag for a solo travel expedition along the coast of Italy. I love to swim, but I wasn't comfortable with the idea of leaving my belongings abandoned on the beachfront. I was looking for something that was durable, affordable and didn't take up much space. This dry bag checked all my boxes. I brought it into the ocean with me and absolutely no water got into my bag. This bag is not advertised to be "water proof," but it works absolutely perfectly. I put my ulta-valuables (phone and money) into a small, secondary case within the dry bag, but my clothes, shoes, and towel stayed perfectly dry even without a second layer of protection.While the dry bag certainly isn't compact, it packs down nicely. I was traveling with only a backpack and was able to fit my dry bag plus all my other clothes, shoes, toiletries, etc. no problem.As far as price goes, this dry bag is pretty unbeatable.One thing to note is that I bought a 10 liter bag and it came with the backpack straps and not the cross body strap as pictured. It didn't bother me (in fact I might actually prefer it) but it's something to note. I also never found the waterproof case that it's supposed to come with, but I was packing in a rush so its possible I just lost it. Either way, for 20 bucks this bag is well worth the money.All in all, this bag is a must-have for solo travelers. I can't recommend it enough!
