    • Perfect for travel, rafting, beach, etc
Color: Grey Style: 1 Liter
I love how small and lightweight this is. Perfect for just the essentials while at the beach, rafting, etc. I used it for my passport and phone while I was alone on European beaches and didn’t want to leave them on the beach while I went in the water.

    • Great little waterproof bag
Color: Orange Style: 2 Liter
I carted my valuables everywhere in this bag while walking in Spain. It was big enough for my phone, wallet and passport. The clasp creates a handle to hang from hooks in showers or onto things like paddle boards. The bags are made of super fine nylon and have a pleasant feel to them, I often tucked it into my sleeping bag. My choice of red helped me not forget in. ... show more

    • can see through it
Color: Orange Style: 2 Liter
really thin and you can see the contents inside. I am not sure how the screw in the replaceable buckle will hold up.I never had a problem with the old style breaking. Contents did not get wet after being left out in a 9.5in rainstorm.

    • A quality dry bag.
Color: Grey Style: 13 Liter
Ok well shipping was fast of course. I purchased the 13L for my section hike of the AT. Wanted something that will hold all my clothes other than what I will be wearing and the size I believe is perfect. Puffy jacket, change of underwear, Socks, another outfit, base layer and anything extra that will need to stay dry. I filled it and ran it under the sink for a few mins and everything was dry so I don’t have any doubts what u put in will stay dry so that concern is no longer. I wouldn’t submerge it but under normal use it should be fine. I also sprayed the seams inside and out with waterproofing for just an extra layer of protection, which it probably didn’t need it. As for the build quality, it’s perfect. Typical Sea to Summit, good quality. It seems thin and it is but it also seems that for what I’m intending to do with it it should last many seasons unless I snag it on something. Not to fear it is of good quality. Buckles are nicely made and fit together very good and can be replaced if in time that becomes necessary. This bag weighs next to nothing so for Ultra lighters it’s great. My suggestion is that if u wanna use it for clothing to stay dry for hiking it’s perfect. If u wanna use it for a food bag, I would recommend using Dyneema instead. Unless u are not worried about animals and such. This dry bag will not hold up to mice, critters, bears etc. But to keep the contents dry this bag is a no brainer. Dry, light weight and build quality it’s the one to get. Just pick the size u need. Hope this helps. I’m happy with mine and u will be too, just use it for what it is intended for. As long as u don’t submerge it it will be completely water repellent I’ve tested it. ... show more
