This is the perfect size for a days worth of snacks plus my headlamp while canyoneering. It's very lightweight and to my surprise totally waterproof (as it should be). I couldn't imagine such a thing material being waterproof but after being repeatedly submerged for 2 days in a row this bag didn't leak once. I'm very impressed and would recommend to anyone looking for a small, lightweight, and waterproof bag.

Benutze die dry-bags von sea to summit schon Recht lange und hatte sie auch auf einem thruhike (über 4000km) dabei und es ist noch kein einziger kaputt gegangen. Man sollte nur vor Beginn einer Tour die Schraube am Verschluss kontrollieren.

ultralight drybag. it's sturdy and water tight. Due to material thinness I could see it being easily ripped if put in a pack with gear that has any kind of sharp edge.

Used 3 of these for our personal gear on a 9 day, 101 mile canoe trek through the Boundary Waters.These worked great and kept our clothes and sleeping bags dry even though the bags they were in got wet every day sitting in the canoes as we paddled and got in and out of the canoes as we made an average of 6 portages a day.Highly recommend these bags if you plan to use them in another bag. This material is very thin and not likely to stand up to the abuse the thicker dry bags are made of.

Nice sack, but I had to return the 8L one since it was too big. The Amazon dimensions are pretty off from reality and what’s actually written on the product package - see photo.Per Amazon website 8L is 7.75 x 14.5”.Reality 6.7 x 18”.

I ordered orange, and the label on the packaging says orange, but this is definitely a red bag! Otherwise it is as advertised. Silicone based water proofing is easier and more standard to repair, and matches the rest of my kit. I like that it has replaceable clips- no sewing or sealing if one breaks.

Use this to store my rain coat to store on my bike and it works great. Supper light and packs up real small if you are not using it. Kept my coat completely airtight. The material seems a little lite so it might not be good for anything rugged but I have not tested that out yet so that may not be an issue.If you need a light dry bag then you cannot go wrong for the price.

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.
