    Durable

    • Familiarity: I've put it through the wringer

    I've had one of these in the small size for years, that used to perfectly hold a full-size down pillow. Now I use it as my Uh-oh kit bag, that holds things like a Voile strap, multi tool, flint/magnesium strip, lighter, DEET, etc. It gets tossed around, stuffed into the pack, and keeps on kicking. I just ordered another one in XS, that will replace my size small as the Uh-oh bag, so the small can go back to pillow duty.

    Great sacks

    • Familiarity: I've put it through the wringer

    I have several of these for puffy jackets that can't be stuffed in a pocket. The 4L size is perfect for full jackets and pants. The 2.5 is great for vests. I really like how they come in different colors so I know which jacket or pants I am pulling out.

    Perfect for an oddball use...

    • Familiarity: I've put it through the wringer

    I use these to keep the pressure tubing organized in my blower-door test bag. They are color-coded to the tubes and save countless tangles and frustration while providing lightweight protection from other stuff in the bag. I like the sizes (Small holds two 35' hanks of 1/4 ID poly tubing with room to spare), the colors match my needs (Red, Yellow, Green Blue), and I appreciate not having a lid floating around to get in the way when I load and unload. I was a bit worried the silicone might catch on the tubes, but it slides in and out just as easily as other stuff sacks with (for example) white interior coatings.

    Jetboil Cozy

    I use a Sea To Summit Ultra-Sil Stuff Sack (size xxs) to keep my Jetboil Ti stove and an extra 100g fuel cylinder tidy. After a meal on a recent trip, it began to rain and I slipped the Stuff sack over the assembled Jetboil to keep its neoprene sleeve and burner dry. Worked like a champ!

    Jetboil Cozy

    Fits my sleeping bag

      I bought the 20L stuff sack after having an oversized stuff sack for a few years. I tend to stuff my sleeping bags into the bags tightly (my sleeping bag is closer to fitting in a 22L bag instead). The only thing I wish this had is a cover flap around the drawstring area.
      The next thing on the list is to see how all my stuff fits into my truck box....

      Super light

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

      These are just what I was wanting. Super light, and yet hold air when folded shut, so the 20 liter should be great at keeping water off my sleeping bag in the backpack, and the 4 liter is my new food bag. Just a heads up for those not familiar with the material: it is super light weight and must be protected against pokey things, or it will get holes and leak. Treated properly, I believe I'll get many years of good use from these.

      You can never have too many of these!

        They are light, strong, keeps your stuff dry and organized.



        I have so many to hold clothes, wet jackets, climbing gear, slack lines... you get the idea.



        For a size reference: the small holds 80 feet of 1" webbing, two 10 foot sections of 1" webbing, 4 carabiners and 2 rap rings. And there's still a little room to spare.



        A little more expensive than others but worth it in my opinion. I only wish we could choose the color.

        Sea To Summit XS Ultra-Sil Stuff Rocks!

        • Familiarity: I've put it through the wringer

        I've been using the XS Ultra-Sil Stuff Sacks for years. I use one as a stuff sack for my "regular" Therm-A-Rest Prolite Pad (fits perfectly). I use another as a storage sack for my cook set (Jetboil Sol Ti, Jetboil spoon, extra Jetboil 100g fuel canister, plastic REI bowl). These stuff sacks are light (0.50 oz) and get the job done. What's not to like?!

        Not what I thought....but it works

          The only downfall to me about this product is when I looked at what was being advertised I thought I'd get around three stuff sacks, however when they came in the mail turns out you really only get ONE! Other than that the stuff sack that I did get was awesome when I used it for my clothes. I was really surprised at how much it could hold.

          Decent product

            Bought one of these for my first aid kit and toothbrush etc. on a hike through the White Mountains. The bag works great...that is it holds your stuff. But I found myself wondering why I didn't just stick my stuff in a Ziploc. Will work great if you want to color code stuff in your pack with all kinds of little bags, but essentially all it is is a glorified plastic bag.

            G'Day noj -

            We're probably a little biased (after all, we are the manufacturer), but here are some points which we like about Sea to Summit UltraSil Stuff Sacks which we haven't noticed on Ziploc bags:

            - made of tough, siliconized Cordura fabric (will not snag like PE film)
            - available in sizes from 2.5 all the way to 30 Liters
            - equipped with a separately sewn-on drawcord channel; the opening of which is 180° away from the side seam. The drawcord doesn’t stress the seam
            - equipped with a hypalon tab with a die-cut karabiner hole to help you hold onto and hang up your stuff sack
            - available in 6 colors to help you sort your gear

            nice 15L sack for 3 days clothes and nice pillow

              I had that for 3 days Brazilian winter camping at Itatiaia National park in Rio de Janeiro. The weather normally go under -5C. The sack fits all I needed to survive for 2 nights. I definatelly recommend this product for campers.

              No lid

                True to stated weight and size.... check.
                Handle on bottom .... check.
                Really water resistant .... Check.
                Good micro cinch lock to keep it light .... check.
                Lid? Where's the lid? I need a lid when I over-stuff this sack! Good Sack anyway!

                BackCountry gets a thumbs down on this for NOT changing the picture; This is not a roll-top sack.

                don't go by the picture

                  Just so you are aware, the picture above is incorrect. The Ultra Sil Stuff Sack does not have a roll top closure but rather a draw cord with a standard small cordlock. In actuality, it looks and feels very similar to the stuff sack that the Therm-a-Rest ProLite 4 sleeping pad comes with.

                  Regardless, it's a pretty handy stuff sack. It's very lightweight and it's waterproof - two important characteristics in the backcountry. There is a handle on the bottom (closed) end which is handy for carrying it and it seems pretty durable. I keep my sleeping back in mine and it works perfectly.

                  Too bad most of the reviews downgrade the bag because Backcountry apparently screwed up the description. For anyone looking for a rolltop bag, Sea to Summit makes several different types, my favorite being the waterproof (but not submersible), eVent Compression Dry Sack.

                  decent

                    Stuff sack is not exactly what I was thinking I would get. As the last review stated the xs, which is what I oredered, and the L (I suppose based in their review) don't have the roll top closure. I wasn't exppecting a cinch cord. I guess I can understand that on the xs, but on the L...???? Just don't understand the logistics of that one. At any rate, I was going to need a stuff sack about this size and the cinch cord instead of the roll top band makes it a lil more light weight so I'm not going to be upset. However, BC SHOULD look into changing this listing to clarify this issue, cuz I REALLY did need a stuff sak with roll top closure about this size for electronics and such. It gets 3 stars, not because it isn't a decent product; it is. 3 stars because it is only adequate, not extraordinary!

                    Why do you have the wrong picture of this...
