Description

The dry sack from the future.

The Sea-to-Summit eVAC Dry Bag uses waterproof and breathable eVENT fabric to keep your gear bone dry. It’s like a compression sack, but the design allows you to simply push excess air out the bottom eVENT panel as you roll down the top. No more compression straps, no more busted seams from reefing too hard on said straps. Oh, and get this: they’re oval, so they won’t roll off the deck and float down the river without you.

What size for a DSLR (Nikon with longish lens)?
Many thanks!

I can fit a D3100 with an 18-55 in a 5L with plenty of room to spare, so you could probably manage with a 3L if you're just looking to put in a similar sized camera/lens combo. It is useful to pack the lens and body separately if you don't mind the extra lens and body cap, and also if you're not going to be taking it out every 10 minutes.

I would recommend looking into S2S ultra sil dry bags. The eVac is a little more expensive because of the eVent material which for a camera you really don't need anyway. The ultra sil dry bags do just as good of a job and weigh less

I just bought two of these to compress my down jackets and keep them dry in my packs for climbing, hiking, camping etc. They do their job well, however, it has very limited compression capabilities. Not because the process doesn't work (push air out, stuff gets smaller, piece of cake) however, as far as compressing garments, when you press down and try to roll the top its hard to roll it as far down as you want to because (at least in my case) the stuff inside gets caught in the roll. I've only done it like 5 or 6 times now, so maybe I just suck at it.

I find doing a roll or two then shaking it a bit helps keep the stuff inside from getting caught in the roll. It just takes practice.

This is the second evac dry sac I have purchased - they are awesome! I like that it is lightweight and compressible. It is a better alternative to non-compressible dry bags made of heavier material.

So I'm going on a 7 day survival trip next month, and it's been almost 10 years since I've gone camping so I'm getting all new gear. I've found a sleeping bag and mat that I'd take along, now I'm just looking into dry sacks that would be able to hold my belongings. The people I'm going with were reccomending using 2-3 dry sacks (1 for the sleeping bag, 1 for the sleeping mat, extra change of clothes, and other small things that can't get wet like camera etc.) What Litre bag should I look into getting?
If it helps I'm getting item #MHW1203 for sleeping bag and #CAS0504 for sleeping pad. Don't really want to have 1 HUGE dry sack to stuff everything into as it could be easier to consolidate everything into a few.
Thanks!

The stuff size for your sleeping bag of choice is 8 x 16 in. So, based on that, probably a 13L Dry Sack to stuff it in. I don't know that you need a waterproof sack for your sleeping pad, but if you do, check out the Granite Gear ToughSacks, item GRG0084. They have sacks specifically designed for sleeping pads: 11L Tall and 16L Tall. Hope this helps you out, and good luck.

What size bag will fit a Sierra Designs Pyro 15 degree 600 down bag in long? Sierra Designs says stuff size is 18" x 8" so I got the 8L 17" x 8" x 5" bag which doesn't fit. I roll up the sleeping bag as usual but I can't get it through the opening of the dry bag, which measures about 10.5" (when flat) or about 8" in diameter if you hold the opening open in circle. So it's supposed to fit by Sierra Designs specs. So does anybody know what bag size will fit? Space is at a premium, so smaller is better, but without having to spend a lot of time trying to get the sleeping bag in. Thanks!

Don't roll up your bag. Just stuff it in. Then it'll fit. The actual stuff size of your bag is 15L, not 8. 18 (length) x 8 (diameter) works out to 15L. Also, get the S2S Ultra Sil Compression Sack, not the eVac, it'll work better for stuffing.

pho5504966

Hey thanks James! I tried stuffing it in without rolling it up and it still won't fit. You're right, the dry bag is too small and doesn't have the volume to hold the bag. So it looks like I'll have to get the 20L now. I don't care for most compression sacks, because they try to squish the sleeping bag into more of a round shape. I like the traditional "roll" shape (long and narrow width), which fits better into my pack. Thanks again for your help!

I’ll preface this review with my cut and paste statement that I work as a backcountry backpacking guide in Yosemite National Park. Nearly all of the products I take the time to review have seen at least a half a season, if not more, of use... and I’m committed to not bothering to write a review until I feel like I’ve really gotten to know a product. I never thought I’d bother to write reviews, but I’ve recently decided that since I’ve spent so much time over these last many years reading reviews, and finding a tremendous amount of value in articulate and well-informed opinions, that I wanted to give back to the community. So, with that being said, here we go...

(If you don't want to read this next part just jump down to the last two paragraphs.) So, a quick story. I was reluctant to be converted to using down bags and jackets after having spent so much time living in the south. I had just moved back to California to work in the Sierras, and my mentor really tried to get it through my thick, caveman brain that down is the way to go in the Sierras, as its generally very dry. Well, needless to say, my mentor was right. I saved some weight and space in my pack, which I really appreciated.

However, this little paranoid voice kept whispering in my ear, 'What if you take a dive during a creek crossing? What if something happens?' So, to indulge my fear I bought a couple of these for my down bags. Sure, I could use a trash bag, but these make great watertight compression sacks for down bags... keeping it dry and packed down tight.

Well, my last trip of last season, was in the middle of September. Summer's drawn to a close, and the weather is a little less predictable in Yosemite by this time. Sure enough, it rained almost the entire trip. We had people ready for rain... pack covers on, jackets and bags wrapped in trash bags, etc. Well, we arrive at camp on day three. It had been pouring for over five hours, so it wasn't a huge surprise to find some folks with damp sleeping bags once we got to camp and unpacked. Luckily, the rain had stopped, so we made a fire and got some things dried a bit... dry enough that the night wasn't too miserable.

Well, my fellow guide (who was leading the trip) and I had been so busy getting things settled that it wasn't till after dinner that I was able to empty my pack and get my tent up. Well, my pack was soaked. My pack cover had done little in the way of keeping the torrent out. However, in the pool in the bottom of my pack was this faithful dry sack, with my perfectly dry, crisp Western Mountaineering bag just waiting for me. I felt like I was unpacking Claire Forlani to curl up with that evening. That dry bag was the most welcome sight I had seen in a while. And what had provided me such a warm, fuzzy, pleasant night...? A $20 dry sack.

Would you pay $20 to not have to sleep in a wet bag? This may sound funny, and it could have been... but such a situation can be potentially life-threatening. I will never pack a down bag in anything but one of these dry sacks. Ever.

Now, with that story out of the way... I will also add that these bags are incredibly durable. I've beaten the hell out of mine and the stitching, seams, fabric, roll-top all look brand new. And, keep in mind, that's with me placing this dry sac on some nice abrasive granite and mashing my sleeping bag into it like the Samsonite gorilla. I suspect I could make one of these last a decade with some care.

So, in short... is it worth approximately $20 to $40 to you to have something as important as your sleeping bag, clothing, jacket, or food stay perfectly dry despite an accident or adverse conditions? Mmmhmm... thought so.

Judging by what sizes are available, I would go with the 20L. The 8L could be too small for some bags (0°-15°F). These compress down nicely, and the 20L will have plenty of extra room just in case you need throw in a down jacket or some cloths as well.

Banning Lyon

I use a 20L for my Western Mountaineering Antelope, and 13L for my Versalite. The Versalite packs down quite small, so I would imagine the 8L dry sack will only accommodate sleeping bags that are rated around 30-35F and up.

I'm looking for an uber tough really large dry sack to line my 35L pack. Would this product fit the bill? Any other recommendations? I am not super concerned about it being absolutely waterproof but would find that a nice perk. Is this product super durable even with the sharp corners of prepacked food?

This would work. It should be tough enough for most gear (open knives and pointy things excluded). The other one to consider is the Pacific Outdoor (http://www.backcountry.com/pacific-outdoor-equipment-dry-cylinder-dry-bag-915-2136cu-in). It is equally tough, but has a clear window so that you can see what's in the bag and where in the bag it is. A huge help!!!

Phil Maher

As Sandy says, this is fairly tough for most gear, but "Uber tough" it's not. You'll definitely pick up some weight in the process, but the best thing for what you're looking for is going to be the SealLine Black Canyon Dry Bag (item# CAS 0573)...now that's uber tough with an attitude.

A couple other serious contenders are-
SealLine Storm (item# CAS 0607)
Outdoor Research Durable (item# ODR 0470)

You could always go the cheaper route and use extra large heavy-duty garbage bags to line your pack with. It gets the job done and is lighter than any of the other bags listed. Some even have a "stretch factor" included so that they won't puncture right away if they get rubbed the wrong way on the corners of prepacked foods, etc.

I have an REI Flash 18 (18 liter pack) and am wanting to get one of these packs for the stuff I don't want to get wet; Big Agnes Pitchpine bag, change of socks, etc. Should I get the 13L or the 20L? Thanks!

Angus Bohanon

Member since 
Responded on

I'm not sure why you told us about the Flash 18. If you want to put one of these in that pack, you should probably get the 13L because then you know it'll fit. You could also get the 20 and then just not fill it all the way. If you're looking for something similar in capacity, I'd get the 20 because it's obviously the closest in size. If it was me, I'd probably get the 20 and use it as sort of a liner, then roll it shut and clip it and zip the pack over it. Your call though.

adam.cuthbertson

I just mentioned it because I figured some of the people that shop here probably shop at REI as well. The 18 liter seemed to be kind of in between the 13 and the 20 and I just wasn't sure how much "space" the bags take up on their own, unfilled.

I think I'll go with what you suggested though and check out the 20, thanks for the advice.

Yep, like Angus said- get the 20L and use it to line the whole pack-you know everything fits and everything stays dry. That extra couple liters can just be rolled over.

Does the eVAC sack have a bottom strap I can put a line through like the regular stuff sacks? I'm wondering if it would perform well as my food bag if being strung up on a line every night for 4 months.

Phil Maher

No straps across the bottoms on these, but you have a couple other options. When you roll the sack over and buckle it, it forms a solid loop that you can pass your rope through or hook a caribiner on. Also, if you look at the photo above, you'll notice a small plastic eyelet next to one of the buckles, that will work the same way. Sort of an expensive potential pinata, but it should work as well for hanging food as anything.

The work really well as compression shacks and they are watertight all they way but after only a 4 day trip in the white mountains last week one of the sacks i bought was already starting to have a wear hole so i'm not sure how durable these are.

G'Day Ethan

sorry to learn that your eVac Dry Sack is looking a little worse for wear.

As you'll gather from the number of positive reviews on this page, the overwhelming majority of users never experience wear issues with the eVac Dry Sacks at all - so I'd be interested to learn a little more about the conditions the bag was used under.

Please email me directly at barry@seatosummit.com - I promise to work with you to find a reasonable solution.

Cheers!

Dry sacks are something I generally take for granted, but even with that said, this is so much better than anything else I've used it's incredible. The eVent bottom means that compression straps are now pointless, as by creating a vacuum, you can squeeze out just as much air as you could with the straps. As an added bonus, because there are no straps, you can "mold" the bag into different shapes, instead of just a round ball. As an example of how sweet the vacuuming is on this bag, I managed to compress my First Ascent Downlight sweater down to around a liter inside this thing. As a warning, because you can compress clothing so much, especially down, it's possible to push feathers through the fabric because of the added pressure.

I only have one of these that I use to keep my down jacket in. I wanted to make sure that it was not going to get damp or damaged in my pack and this bag is a peace of mind to me. I have the 8L and that works fine for Patagonia down sweater.

I use an 8-liter bag for my mont-bell Alpine Light Down Jacket. I could go smaller, but it's nice not to have to fight the bag every time.

While the included stuff sack is lighter, it's not waterproof, and that's important to me with my down jacket in the mountains. And a compression sack would allow me cinch the bag and my jacket down, but volume isn't an issue for me. Some folks need to compress their down sleeping bag and/or jacket down to its smallest size to make room in their pack. I prefer not to do that, as I think its better for the loft of the down item, and space isn't an issue in my pack.

Additionally, the extra straps and buckles on the compression sacks always add quite a bit more weight to the bag, at least a couple more ounces. At 2 ounces, this is a nice insurance policy for my puffy.

Excellent review! You have a great point! All of us are brainwashed that everything needs to be compact as possible to be the lightest or the smallest, but when it comes to down for example, it may stress its loft.
Thanks!

My dream drybag is here in the Sea To Summit eVac Dry Sack. It is light-weight and highly compressible. The bottom panel easily expells the air inside the bag (and keeps it out!) and the light-weight material the sack is made out of allows the bag to compress very tightly almost eliminating the need for a compression bag. The bags come in various sizes so keeping my winter mountaineering down sleeping bag dry or my lunch in the day hatch of my kayak dry has never been easier or more assuredly DRY.

Awesome bags! I bought this 60 miles into my thru-hike of the AT and never looked for another bag to keep my camp clothes and sleeping bag dry. I bought this because my rain coat was made out of the same Event fabric and loved its air flow quality...makes getting air out of those sacks so much less of a technique. Very light weight and durable still using it!

I own several Granite Gear dry sacks which vent when rolled up like this one. The Sea to Summit is every bit as good, but slightly heavier. Granite Gear unfortunately is not making theirs anymore. Very good bag that compresses well while keeping any water out. Like most stuff sacks this one is overpriced terribly. It would be great if they would come down in price.

What is the difference between the eVent Compression Dry Sack (Item #STS0002) and eVAC Dry Sack (Item #STS0043)? I know that eVent Compression Dry Sack is more expensive than the eVac Dry Sack. Does it mean eVent Compression Dry Sack is more waterproof than the eVAC Dry Sack?

The compression sack allows you to cinch the bag and its contents down (compress) in the event (no pun intended) that volume is an issue for you. Some folks want to compress their down sleeping bag and/or jacket down to its smallest size to make room in their pack. I prefer not to do that, as I think its better for the loft of the down item, and space isn't an issue in my pack.

Depends on the volume of the sleeping bag when it's compressed down. The 20 L (next size larger) sack should probably fit your bag along with maybe some other items (spare clothes perhaps). I pity you for having to haul around that massive sleeping bag.

Most sleeping bags should fit in the 13L size except for the heavy duty synthetic winter bags which should fit in the 20L. Expedition bags may have to step up another size from there.
