Your cart is empty.The Sea to Summit Evac Compression Dry Bag is a lightweight, roll-top/compression strap dry bag with an air-permeable base—air can be pushed out, but water can’t get in—and four straps for even compression. Ideal for backpacking, sea kayaking, and travelling, the valve-free expelling design works along with the straps to compress bulky clothing or gear, by rolling and pushing out excess air and cinching down the straps. Manufactured from bluesign-approved lightweight PU-coated 70D nylon, and a 40D nylon air permeable/waterproof base, with a 10,000mm waterhead (the higher the waterhead rating, the more waterproof the fabric), its reinforced waterproof seams are double-stitched, and tape sealed, with reinforced stitching at stress points. A waterproof Hypalon roll-top closure, and four straps featuring two ladderlock and two side-release buckles, keeps gear compact and secure. The Sea to Summit eVac Compression Dry Bag’s low-profile, streamlined shape saves space, and its oval base resists rolling. A patent-pending field repair buckle can be replaced in seconds with a Phillips screwdriver. Available in five sizes: 5 liter, 8 liter, 13 liter, 20 liter, and 35 liter, to carry everything from small essentials to group gear. Sea to Summit products are guaranteed against defects in materials or workmanship for the lifetime of the product.

Awesome compression bag. Two straps have disconnect buckles, which makes packing and unpacking easy. Strap across bottom is good for retrieval from deep bags. Have not yet tried if it’s waterproof.

I recently used the Sea to Summit eVac Compression Dry Bag on a backpacking trip, and it has quickly become one of my favorite pieces of gear. This compression sack is an exceptional blend of functionality and durability, making it perfect for keeping my gear organized and protected.The waterproof feature is a game-changer. The bag kept my entire Zinbevy sleep system completely dry despite some unexpected rain and damp conditions. The quality of the material is evident; it feels sturdy and well-made, and the roll-top closure ensures a watertight seal.The compression aspect is equally impressive. I was amazed at how efficiently this bag compressed my sleep system, saving valuable space in my backpack. It allowed me to pack everything down neatly and fit comfortably within my pack, which is crucial for long hikes.The design of the eVac Compression Dry Bag is user-friendly. The compression straps are easy to adjust, and the bag’s lightweight construction doesn’t add unnecessary bulk. Additionally, the bag’s sleek design and color options add a nice touch to its practicality.In summary, the Sea to Summit eVac Compression Dry Bag is a top-tier product that delivers on its promises. It effectively compressed and waterproofed my entire Zinbevy sleep system, proving itself to be a reliable and essential piece of gear for any backpacker. Highly recommended for those seeking excellent compression and protection for their gear!

Bought this for hunting. It fits the new Sitka 15degree bag. Seems like good quality and a nifty design.

neat compression bag. everything fits together, it will compress down, doesn't let air back in, and the colors stand out.just concerned about the long-term durability. the material is rather thin. don't use this bag for anything with sharp or rough edges, don't drag it across the ground. light water sheds off of it, i wouldn't trust it with a dunking or laying in a puddle.it doesn't seem to go on sale, but it does have coupons now and then. watch for a discount and then pick one up.

These are really good compression sacks. Very well made, waterproof, and the venting system prevents wasting pack space on trapped air. I have three of them in various sizes:35 LITER: I use this monster for a Therm-a-Rest Saros 0f (long). The Saros is a very large, roomy sleeping bag by design, even in the regular size. It's also a full synthetic, making it even more bulky. The long is both longer and wider than the regular and it fits well. A down bag, especially if it's high fill power down will probably not need a compression sack this large.8 LITER: I use this primarily for a Rab Ascent 500 (wide). This is a 650fp down bag with a 34f comfort rating. It does fit, but it's tight. Should fit a regular easily. Also fits a Sierra Designs Get Down 20 (regular), which is 550fp down. So, this should be good to go for any traditionally designed down bag in this temp and fill power range. It works for a Sierra Designs Nitro 35 quilt, too, and that's 800fp.5 LITER: This one is good for my 50f comfort rated synthetic rectangular summer bag. It fills it up, but I can still roll down the top and get some decent compression out of it. If it works for that you can bet it's going to work for all bags in this temp range regardless of shape and fill material. Unless it's super bulky cotton, of course. It's also good for packing thermal layers, extra socks and underwear, a puffy jacket, etc.One thing you should know is that these are not cylindrical in shape, but rectangular. Once you pull them down they do take on a somewhat cylindrical shape the more you pull down the straps, but if you don't jam them full and compress them as tight as humanly possibly they'll stay relatively flattish which I think uses pack space more efficiently. Even the 35 liter with the humongous Saros bag, I can lay my body on it to expel the air and pull it down just enough that it fits in a 75 liter Gregory Baltoro with plenty of room left over for multiday winter backpacking. Tent on the outside, of course, and, yes, I backpack the crap out of that nearly 6lb sleeping bag.I highly recommend these and if you don't need one right away, just keep your eyes on them for a sale because they're not cheap. I got all three for 50% off and they were definitely worth it. DO NOT compress them by pulling down the straps unless you just want to tear the straps off. Compress them with your body weight and then cinch down the straps.

These compression sacks are amazing. Really stuff your sleeping bag into a small space and keep it dry! No trapped air like other stuff sacks. Used on a canoeing trip and in the rain. No issues. I wouldn't use it alone on the water though. Our sleeping bags are double bagged in a dry sack when we canoe. But for backpacking I use this in my pack with no worries.

Some folk don't like stuff or compression sacks for hiking, but my partner and I bought these as an experiment and we found them highly valuable. Sleeping bag, liner and sleep wear went in, packed down well in the bottom of the bag with few gaps, and ensured everything was nice and dry when setting up camp. Whilst we could have used a bag liner, this had the added benefit of keeping everything separate from damp or smelly gear, made setting up the tent easy in the rain because we could keep bags outside whilst moving all the sleep gear in nice and dry, and also served as an excellent cuddle pillow each when stuffed with our camp clothes (we're both side sleepers). Highly recommended.

I’m using this for motocamping (motorcycle) to hold tent (Big Agnes 2 person Copper Spur) and sleeping bag (Featherstone Moondance Quilt), which is what is in picture. This will be strapped to rack on motorcycle. I did not see until after I purchased that S2S makes a compression bag out of heavier material. While this will work for short term, I prolly need the HD sack for better durability. I’m sure this sack is as advertised, so I’m giving it five stars.
