Durable and Reliable
I've recently purchased my second Sea to Summit Lightweight Dry Sack, and it continues to be one of the best all-purpose dry bags I've used. My first experience with this dry sack was during my time in the military, where it proved indispensable for keeping electronics and valuables safe and dry under various conditions. The quality and durability of this dry sack are outstanding. It withstands rigorous use and effectively protects contents from water, dust, and other environmental elements. The lightweight yet robust material is a significant plus, making it easy to carry without compromising on protection. The second dry sack I purchased has found its place in my ATV, serving as a reliable storage solution for phones and other valuables. It excels in keeping rain and dust out, ensuring my items remain dry and safe even during off-road adventures. What sets this dry sack apart is its versatility and reliability. Whether it’s for military use, outdoor adventures, or simply for keeping valuables protected from the elements, the Sea to Summit dry sack performs exceptionally well in all scenarios. In summary, the Sea to Summit Lightweight Dry Sack is a product I highly recommend. Its performance in keeping items dry and secure, combined with its durability and ease of use, makes it a must-have for anyone needing a dependable dry storage solution.

Dry bag… AND an ice pack?!?! Whaaa!!!
So besides being a great light weight dry bag, blah blah blah. It also makes an amazing ice pack!!! We did a kayak-in trip with a short hike through creeks and other slippery areas, ended up with a possible knee injury. Got back to the hotel and was about to use the hotel trash bag as an ice pack when suddenly I thought “why not use the dry bag?? If it can keep water out… that means it can keep water in!!!” By golly it’s the best thing since sliced bread. I filled that sucker up with hotel ice from the machine and secured the top. Viola! Leak proof, flexible. Doesn’t drip at all. Amazing!! Highly recommend! As a dry bag AND an ice pack!!

Send it!
I purchase multiple sea to summit bags for my 2020 Thru Hike of the AT. These bags were awesome and I never had one instance of water inside my bag from Georgia to Maine. I did take extra precautions by using a contactor bag to line my pack as well. I had two 13 liter bags, and an 8 liter bag. I used one 13L for sleeping gear (it easily fit a 0 degree down enlightened equipment quilt, thermarest bag liner and an inflatable pillow). The second 13L was my food bag. I was able to fit around 5 days worth of food, but it was a bit of a squeeze. Once on trail I purchased an additional 4L sea to summit bag to hold overflow food. I ended up keeping this bag on the outside of my pack and I kept my snacks, and lunch for the day in it so I didn't have to dig through my pack or my food bag during the day. I needed the extra bag to get all of my food/smellables to hang it every night. **I purchased the 4L bag from an outfitter on trail, it held up pretty good, but did not last the entire trip. It was made from sea to summit's ultralight material (a much thinner material than this product) and it developed a slice in the material. Eventually a mouse chewed through it and got to my food - I always hung my bags** I would probably get a different bag or a slightly larger bag if I were going to thru hike for a stretch that long again for my food. I used the 8L bag for my clothing. As I am a petite woman, my clothes didn't take up too much space, but during my winter hiking months it fit my puffy, long sleeve sleep shirt, merino wool pants, spare pair of underwear, two set of darn tough socks and two sets of sock liners. I have seen people wash and dry these bags in machines with no issues. These will continue to be my go to dry sacks.

Water resistant, not proof
I used this bag as an external storage bag for food on a long hike. We also used it to hang our food at night. Worked fine for this, and the water resistance was put to the test during a ridiculously bad rainstorm that lasted several hours. While the interior contents were damp, the bag did at least keep the book of the water from getting inside the bag. Use a second layer of protection like I did if water proofness is paramount. Bag is very lightweight.

I liked it enough to buy more
Bought it during a sale that made it worth the extra $ to purchase a name brand. The manufacturer on their website admits that of the three basic drybags that they offer, this is in the middle for weight and durability. As for being waterproof, the manufacturer states this: "The body of the dry bag is waterproof (10,000 mm hydrostatic head). However, avoid submersion since water can seep through the roll-top closure of any dry bag." I don't plan on submersing the product as I bought it to be used as a liner for my back pack to hold my sleeping quilts and extra clothing. I didn't realize it when I ordered the product but it has a white interior. This is really nice if you plan on putting small items in it as it makes the interior more visible. Regarding durability, the product has a lifetime warranty against defects. Recently I had to deal with Sea to Summit's customer service for a different item that I purchased. The customer service attention to the issue was outstanding. Email replies did take a couple of days, but the issue was resolved above and beyond expectations. Granted warranty against defects *DOES NOT* include issues resulting from normal wear and tear and misuse, but I wouldn't expect such a warranty. As a result of the customer service, I took advantage of their Black Friday pricing and bought two more drybags of different colors & sizes. (I bought the ultra-sil instead of the lightweight version this time.) They should arrive in a couple days. I own a few Sea to Summit products and when the price is right, I will choose them over the cheaper questionable brands. Their pricing is such that for most of their products, I would not pay full price.

Diese Säcke sind immer im Urlaub dabei - Die verschiedenen Farben helfen, Dinge schnell zu finden (dreckige Wäsche, Waschzeug etc) die Schlaufe ermöglicht ein Aufhängen überall, ob Segelurlaub oder Badezimmer. Zwei liegen in meiner Sporttasche als perfekte Aufbewahrung für feuchte Schwimmsachen und für das Waschzeug. Ich benutze die Beutel seit Jahren - sie sind unverwüstlich- ohne dass Material oder Verarbeitung Zeichen des Alterns gezeigt hätten.
