Sea To Summit eVAC Dry Sack for Sale, Reviews, Deals and Guides

I have used this on a few river trips and traveling around in Costa Rica and it is great. I got a bigger version to keep all my clothes dry and the smallest version to keep my phone and spare battery chargers dry and it works great!

We bought this sack for the paddle board and kayak. It is super lightweight and packs up pretty small. I'm a little worried about the overall durability because it is such a thin and lightweight material but it seems to be holding up really well to normal use and abuse of the lakes and rivers.

I keep all of my must stay dry items in this bag (sleep system/ layers/ anything down). It has been set in the snow/ wet conditions, and performed beautifully. Nothing has even gotten damp in here. I have not submerged it or exposed it to water for long periods of time, but in regular backpacking/mountaineering applications it has worked flawlessly. The air release system is slow but effective, and i have had no issues with moisture on the vent portion.

I use this sack to keep my 1400ml Snow Peak cook set in. So far the sack has kept it dry.

These are almost as compressible as a compression stuff sack, less money (in some cases), and waterproof! I bought several of these!

I bought the 13L sack because I needed to ensure my bag stayed dry while hauling it up the wall. This thing couldn't be easier to pack and does it's job as advertised.

It works

I have owned several sizes of the eVAC Dry Sack over the years and really love them. The ease of compression is great and they are super light. I believe their application is the key to their success. I use them for keeping backpacking packs and bicycle panniers organized, where some added waterproofness is beneficial. I also use them for storing and hanging food when it's warranted. I would recommend using something more bomber if you expect the sack to be submerged in water or exposed to abrasion for extended periods of time.

I bought the Sea to Summit eVAC dry sack in the 20L size to line my daypack in the event of heavy rain or a river crossing or wet canyoneering. Works like a charm. The weight of the sack is negligible. So, there's no reason not to carry it when there's a chance I might need it. The eVAC integrated one-way valve is a neat addition, kinda gadgety, but ultimately unnecessary for purging the sack and reducing it's space to a minimum if you know the technique for doing so to a river bag that doesn't have one of these valves. I've read complaints about the sack fabric's lack of durability. It sure isn't Codura. But since my use is mostly limited to inside another bag, I'm not worried. I'd use a burlier stuff sack, like the Outdoor Research Durable Stuff Sack which I also have, for applications involving abrasion and what not. But it will add ounces to the kit, so it's a trade-off. For light weight, inexpensive, waterproof protection, I'm a fan of the Sea to Summit eVAC dry sack

For any whitewater kayaker such as myself, a dry bag of sorts is a necessary piece of equipment for taking gear, clothes, lunch, etc down river. Because this vital piece of equipment is used on almost any kayaking excursion, a dry bag (or "dry sack" in this case) should be able to hold up to regular use and at least a minimal amount of abuse. This past Summer I received a Sea to Summit Evap Dry Sack as a gift and initially it worked pretty well despite my concerns about it being so thin. This usefulness was very short-lived; however, and after not even a full summer of kayaking, my "Dry Sack" already leaks like a sieve. Just from the relatively small amount of water that leaks into my kayak over the course of the day, whatever I put in the dry bag will either be damp or fully soaked depending on whether or not i'm lucky. Full submersion with this dry bag is out of the question. For whitewater or any other boating/nautical purposes, these things are absolute garbage and a huge waste of hard-earned money. The ONLY reason I am giving this a 2 star rating instead of 1 is because backpackers that use these dry bags may find them desirable because they are very light-weight. Bottom line: buy a different dry bag. Pretty much anything will be better than this.

This kept my food and electronics dry in a couple wet slot canyons in Utah. The vent feature is great to keep things compact in your pack.

I have several different dry back but it is perfect way to purse the air and pack small while keep weatherproof is awesome. Easy to purse the air out and has been great to take to Paddle Boarding in the ocean, river and lake

My sleeping bag fits into here perfectly. The material seems sturdy and not too flimsy like many other dry sacks I've checked out. I'm using this currently and place my sleeping bag at the bottom of my pack. It is easy to roll down three times and snap closed. good product would get another if i needed

Now that I have upgraded my stuff sacks to lighter and better ones, ( my old stuff were Chiounards which were pretty hard to beat) I have more confidence in keeping my essentials dry.

I had originally gotten this bag for my sleeping bag but decided to upgrade to the compression version. I use this bag for my clothes and outer layers and it works great for that, You can get most of the air out and it has a little compression capability which is nice for packing in a pack. It keeps things dry so it is doing its job.

I'm pretty sure this is my favorite stuff sack! I have the 13L size and I just keep my sleeping bag in it when I'm backpacking. I can attest to the fact that it is waterproof! This stuff sack lets you compress the contents of it by simply squeezing excess air out (and it's lighter than a normal compression sack). I've been using mine for a year and it still looks new!

I have had this dry bag for 3 years now and this past year it started tearing in areas creating small holes. I was on a canoe trip and I threw it out of my tent. It hit a rock and the rock ripped straight through the fabric. For the rest of the trip I used a SealLine Baja bag and the material felt much tougher and worked better. I will definitely buy one for next summer.The buckle on that bag is also much tougher.

I'm not sure how this thing works, but I'm 95% sure it has to do with magic. I have the 20L bag and I can fit my down sleeping bag and big agnes sleeping pad inside of it pretty easily. I can compress it down, throw it in my bag, and keep everything dry, compressed, and organized. The only reason I didn't give it 5 stars is because I'm not in love with it yet.
