Rated 5 out of 5 by from simple, reliable, I've used a few of these in the past on an Appalachian Trail thru-hike, for keeping spare clothes dry, and for consolidating food and hanging it from trees so bears and hungry people who can't climb trees can't steal my food. They work quite nicely for keeping things together and for keeping things dry. I used the 13L ones. Just bought a 1L sack to store the phone, charger, earbuds, and wallet, since those things should be kept dry, and are useful for keeping together. I got the pink one, obviously, because chicks dig hunky outdoorsy guys, and chicks dig pink, so why not combine the two and profit. Anyways, they're worth it. Happy trails.

Rated 5 out of 5 by from Lightweight, simple concept, waterproof- does its job First experience with the S2S Dry Sacks and I have to say I was impressed. Bought a 4L for smaller items toiletries, etc and the larger one- 13L- for food. Kept water out and the almost-see-thru material was nice for scopin' out what was on the inside. Material is reasonalbly durable and I don't plan on dragging it around anywhere. Once I got the hang of expelling the air, the roll-down trick was pretty cool. Was able to use a biner and clip along with a bear bag to hang food as well. Now to get the summer sausage smell out of it.....

Rated 5 out of 5 by from Food kept dry all night in the rain We used the 35L dry sack to bear bag my food, and unfortunately, it rained all night. Fortunately, our food stayed dry (and uneaten by bears). We also used 13L and 20L versions to keep a dry set of clothes in our packs. The packs didn't get wet, so no telling if we averted disaster there, but I feel pretty confident that the sacks were up to the task. ,,,,These are lightweight, easy to use, and very convenient for a number of uses. I will be getter some additional smaller ones for other items to help keep my pack well organized.

Rated 5 out of 5 by from Best Sack I've ever got my hands on. STAFF REVIEW I brought my Sea To Summit Ultra-sil Dry Sack with me on a backpacking trip to Mexico! I used it within my pack to keep valuables safe, such as my camera, wallet, phone, and passport. It was excellent as it’s packable, endlessly reusable and resizable, and fits down in a pack perfectly (1L version). It’s got a really solid roll top, and even after using it abrasively with sand in my pack, bouncing around full of sharp stuff, I happily tossed my phone in it and clipped it to my waist for a trip out snorkeling. It kept my phone safe and dry, and after pushing the excess air out, didn’t act like a giant life vest keeping me floating. It was a solid piece of gear, and I’ve like it so much I now own three of them. I trust my gear in them on rafting trips, while snorkeling, and to keep everything I need dry in a rainstorm when I’m out on the trail.

Rated 5 out of 5 by from Highly recommended! These bags make great space savers in my pack; you can put your spare clothes in them roll all the air out, and your clothes are sure to be dry when you open the bag back up. They are super durable and the buckles work flawlessly. I'm a little OCD when it comes to organizing my pack and these guys keep everything in their place. The different colors are great because I can quickly identify and reach for a bag and know what's in it. Highly recommended!

Rated 5 out of 5 by from Best Idea Ever I don't write too many reviews, but these deserve it. Running a large two compartment bag I've switched all of my gear into these. It makes organization a snap, you can see enough to make out what is in them, tough enough to make two week long back country trips, and I color-coded them by gear type. That and their waterproof and lighter than the stuff sacks you usally get with your gear. In short this is the best thing I bought in a long time.

Rated 5 out of 5 by from Great Stuff Sack for Hiking I use this product as a stuff sack for backpacking. Right now I only have one, but I plan to purchase more. The one I have now is used to store my food while hiking. The stuff sack keeps my food dry which is a big plus for wet nights in bear country where your food must be hung. The fabric is also super light weight. Please note that the product description says it stays dry when not submerged, so I would not recommend this for water sports.

Rated 5 out of 5 by from Amazing i have a 3 person tent, I always had a hard time getting it to compress down to fit really good in to my backpack. I got the 13L one and its just the fight size for a 3 person tent! make sure you push out all the air first before you roll it up! it really compress it down to the size or a mid size sleeping bag in its stuff sack. I love how no air get back in to it so it stays small in your bag and doesn't try it expand.

Are these bags also waterproof if you put wet clothes, swimsuits etc in them...

Asked by: annie29
Hiya Annie29, thanks for your question! You betcha... you can use it for wet clothes and the like. Did you know you can also fill it up with clothes, soap and water and use it like a washing machine? It's best to sing "Shake it Up" while you do it. Hope this helps!
