    Details

    Ultralight, durable, waterproof protection.

    The Sea To Summit Ultra-Sil eVent Compression Dry Sack compresses gear like dry suits or sleeping bags to one-third of their volume while keeping them dry thanks to the eVent waterproof membrane. Ultra-Sil nylon keeps this sack remarkably light for how strong it is, and the Hypalon closure makes sure your gear doesn't slip out. The three Cordura straps shrink everything with ease so you can hop down the trail knowing that you didn't sacrifice any space in your pack.

    • eVent waterproof membrane
    • Ultra-Sil nylon shell
    • Cordura straps
    • Hypalon closure
    • Three compression straps

    Decent compression sack

      I purchased this ultra-sil dry compression sack to use with my down sleeping bag. However, after examining the bag a little closer, I only use it for clothes and other small items now. Where this is a nice ultralight sack, it just isn't as durable as the original event dry sack. The original version has an additional compression strap, with much thicker and more durable materials. Unless you really need to shed a few ounces, I would go with the original version.

      GREAT

      • Familiarity: I've used it several times

      Simply great... have several of these and they´re really well made ... light and waterproof . Once i was totally soaked during a river crossing and my down sleeping bag inside one of these kept 100 % dry as expected. 5 stars for me...

      Even Better

      • Familiarity: I've put it through the wringer

      If you backpack a lot, and haven't been using these eVent compression sacks, you're seriously missing out.
      Beyond keeping gear dry, and compact in your pack, this thing can double as a water-proof bear bag.
      Its also the best pillow solution i've found on the trail. Don't buy a pillow, just stuff this sucker full of all your clothes, and you're stoked.
      The ultra-sil version is noticeably lighter than the standard eVent version.

      Tougher than the rest

      • Familiarity: I've put it through the wringer

      I've had ultralight compression sacks in the past and typically they don't hold up. Seems split, straps tear, and they end up in the trash. These are exceptionally well built. Mine was crammed into my saddle bag on a 6,700 mile motorcycle trip and returned with no wear after a month of use. I purchased the Small size for my WM Versalite 5'6

      One short One strap short

        I got the event compression dry sack to replace my old sack. It works great keeping my sleeping bag dry but it will not compress as small because it only has three compression straps. If it had four straps it would be five stars.

        Flimsy Construction

        • Familiarity: I've used it once or twice and have initial impressions

        This is a great idea, but lacks in construction. Past versions of this compression stuff sack have been great, but Sea to Summit tried to go too light. The buckles are WAY too wimpy and small-- one broke on my first time using this on a multi day ski mountaineering trip and I returned it. It was a bummer to say the least. Also, the stitching and extremely thin material does not inspire confidence when trying to compress your sleeping bag.

        Great way to keep whatever you want dry

        • Familiarity: I've put it through the wringer

        I have a few of these already and use them regularly on backpacking and kayaking trips. Very simple and durable bag. Keeps whatever you have in them dry without any worries. The 4 strap compression is nice because it really lets you crank down and make these bags small.

        Simple. Light. Necessary

        • Familiarity: I've put it through the wringer

        Having a wet sleeping bag is no fun and causes restless nights. I recently upgraded to this compression sack and love it. I even bought one for my girlfriend (now she can carry more group supplies). Win.

        Love it (of course!)

        • Familiarity: I've used it once or twice and have initial impressions

        Haven't taken it on a trip yet, but it seems great so far! Super light, strong, and completely waterproof. I tested it with toilet paper in the sink and it kept it bone dry. Basically, it seems like a lighter-weight version of the 'old' e-vent sack.

        Love it (of course!)

        What size would I need for a sea to summit trek sleeping bag? Thanks. Update I have the 30 degree Trek bag.

        Best Answer

        Hey Michele - Which Sea To Summit Trek TkI Sleeping Bag do you have? 32 degree, 18 or 12? The compressibility will differ depending on the temp rating and amount of insulation but you will most likely want the Medium in this eVent Dry Sack. Feel free to contact me directly with any additional questions.

        Just thought I'd post a comparison pic of the Trek 30 deg bag, the compression bag that comes with it (which I forgot about when I ordered the event bag) and the event bag. I got the event small bag cause it was on sale. The event small is still a bit larger than the compression bag that comes with the sleeping bag, but as Kyle mentioned it has enough room to put your pillow or something else in. The event is nice and will work for other stuff I want to pack as I live in the Pac NW and it can get a bit wet so you can never have too many waterproof bags!

        Unanswered Question

        I have a very large sleeping bag - the Roots Eastern Pines double sleeping bag (66 x 81" (167 x 206 cm) size) and am wondering if this compression sack could fit it?

        Unanswered Question

        I'm looking for a good compression bag for my North Face Dolomite 20° Regular Sleeping Bag. This seems to be the one I might get. Which size do I need? Thanks!

        what size would you recommend for the TNF Furnace 35 bag?

        Hey Jeff,



        So the The North Face Furnace Sleeping Bag: 35 Degree Down in a the long version has a packed size of 8" x 13"



        This comes to be 654 cubic inches or 10.7 liters.



        So for 10.7 liters, I'd suggest the M/14Liters for this stuff sack.



        Shoot me an email if you have any questions at all!
