Review: Great dry bag, 25L great size for smaller people, Comfy to wear with pockets for water bottle - Bought 25L size. This dry bag is GREAT. I was looking for a couple things: 1) outside pockets to hold a water bottle and 2) interior pockets to organize contents. This has both. I am also short, and this size was perfect for me in terms of holding the right amount of stuff and not looking like I was a child wearing a big backpack. First and most importantly, yes, it kept all my contents dry. The interior zip pocket was really useful for small important things to not get lost (cash, passport, etc). The outside zip was useful for low value things I needed quick access to like chapstick. The straps and padding make it super comfy to wear for long hikes and it has a chest strap. It also looks sleek and nice for what it is. I'm a big fan.
Review: Well made - Very well made...40L is a great size!

Very well made...40L is a great size!

### ⭐⭐⭐⭐⭐ Forever the best!
*by A***R on March 26, 2023*

I first got the 25L dry backpack in 2016 because it was less expensive than all the others I’d found, and I liked the olive-green color. I had no idea how lucky I was to find it! I've used it DAILY for 7.5 years (commuting via public transit year-round in Chicago and as an everyday and travel bag—and a great bag for carrying tons of groceries home), I’ve replaced it only once (back in 2019). I feel wasteful saying this, but I could have continued using that backpack probably to this day, but the water bottle holder mesh on that model was too tight to hold my coffee or water bottles conveniently, the front pocket zipper had broken, and I seem to remember the bag started to wear away where I folded it. In the past 4 years of using the bag I currently own, I have noticed some wear: the black water-resistant zipper covering on the front pocket zipper has worn away, there are whisps of material at some places in the seams, and the bag’s coating has cracked in the corners where the top is folded down every day. These changes in the bag have not affected its functionality. I don’t keep anything I wouldn’t mind getting water on in the front pocket just in case, but I’ve honestly never noticed the inside pocket has gotten wet even when walking for miles in rain or snow. The inside of the bag has NEVER gotten wet—truly waterproof, even years in! It’s low-profile enough to wear on crowded buses, the perfect size for carry on or personal item stowage on an airplane, and comfortable enough to wear while riding bikes or hiking for miles. Many people have asked me where I got my backpack from, and I tell them they need to buy it because I can't imagine being happier with any other bag. Sadly, even people I've talked to opt for ridiculously expensive waterproof bags from other companies. Why, why? I can only think those are passing fads, and this bag is here to stay. I recently bought the Island Hopper 38L bag and am psyched to use it on a trip that'll last a couple weeks. I wish the best for this company--and please keep making this bag so that the next time I get to the point I need to replace it, it will still be here! Also, I paid $54 for the 25L waterproof dry backpack in 2016, and today it costs the same. Yayo! I’ve added pictures of the wear & tear—please remember these only started appearing after maybe 3 years of daily use!
