I bought this for a trip to Antarctica. The small boats that take you to shore every day get you very wet with spray, so I used this for my SLR camera. It sat in the bottom of the boat in puddles and was perfectly dry inside. It was a life saver. I also have used in in the rain forest in Peru. I got caught in a complete downpour, and it never leaked at all. Now I use it for my daypack on all my trips because I don't ever need to worry about rain. The only downside is that it is more difficult to get into it through the rolltop, but that's what makes it so waterproof, so you can't have everything. The outside pockets and extra zipper pocket are really convenient.

Bought this for our trip to Italy. Durable and plenty of space for towels, extra clothes, and bottles of wine. Packs up super portable.
Great gift for my folks, they loved it and found it very useful on their adventure!
