    Sack doesn't stay compressed

    • Familiarity: I returned this product before using it

    I bought this compression sack recently, and when I tried to compress my sleeping bag for a backpacking trip, I wasn't able to get the sack to stay compressed, after a certain point the buckles would release, not holding the bag compressed. I used this sack once, and will be returning it.

    Rugged compression sack for car camping

      I really like these bags. We use the cyclone alps bags for sleeping bags, and air mattresses. I use these bags for clothes. We pack sets of clothes by day into mesh sacks and layer them with the last day on bottom. The bags compress wonderfully and we open to grab the next days clothes and off we go. I know other sack are lighter but this one is very well made and rugged.

      Great job

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

      Got this for upcoming backpacking trips this summer since my sleeping bag did not come with a compression sack. I have the marmot angel fire 25degree down bag and the small fits perfectly. This compression sack cut the size from the original stuff sack by half. Not sure what the zippered pocket could hold, when the sack is in use it is pretty tight so it would be hard to get items in and out easily. I think i will put emergency repair kits in there.

      Rugged

      • Familiarity: I've used it several times

      This is a pretty rugged compression sac. It keeps tight throughout travel.
      However, it's not very light. This together with my big synthetic sleeping bag weighs 4lbs and those pounds add up quick. It's strong enough to endure back country hiking, but if you do better with the lightest weight possible, you may want to consider another sac.

      great sack

        This is great compression sack. I got this for a sleeping bag that I lost the stuff sack to. The medium is more than adequate for most sleeping bags (I would even go for a small if I needed a new backpacking sack for a sleeping bag), and with the compression straps, I can pack it down even smaller than the original stuff sack.

        Very Happy With This Compression Sack

        • Familiarity: I've put it through the wringer

        I picked up this compression sack (size M) on sale to use with my 3-season sleeping bags (the heaviest rated down to 10F). I've been happy with how well it compresses each of the bags - I even throw a compressible pillow in there and it works just fine. The bag is very durable, from the fabric to the straps and stitching. I'm confident this thing will last a long while. It cinches well and loosens easily all around. The zipper pocket on top is handy. All in all, a great little compression sack.

        Lacking

        • Familiarity: I've put it through the wringer

        This bag is rugged for sure, I am in no way worried about it getting torn. It just doesn’t compress all that much. Sea to Summit brand does the whole ‘Wow! How did it get that small with all that stuff inside!’ kind of magic. This bag does not. The only way for it to get smaller is to fill it only halfway and then the design of the straps max out. Perhaps it’s over engineered to be both. Sea to summit and other lightweight bags compress brilliantly but need to go in some other bag or they would most likely get a hole as they get tossed around. Alps would not.

        So as a stand alone stuff sack it’s pretty great. It’s rugged as all get out and has two plastic D rings that you could hang it from or to anything. It shrinks a little with the compression straps which is neat for a regular bag. I trust the nylon handle at the top of the bag with whatever weight is inside and I would happily send it up in a tree with food inside while camping. I use these bags for travel and storage.

        Here’s a picture comparison for “science”. I bought a size small Alps and compare it to two other brands as size M/14L when fully compressed they all end up the same size, Alps won’t hold as much and won’t compress nearly enough.

        Why isn't this waterproof?

        • Familiarity: I've used it several times

        I have a big Mountain Hardware Absolute Zero Parka and it needs a stuff sack for a weapons pack for advanced terrorist operations in snowy weather, or if ambushed in winter so must be waterproof. Does anyone know what size stuff sack I need for an Absolute Zero Parka? Thanks.

        Why isn't this waterproof?

        Food Storage

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

        Used the pack for food storage. Was so convenient to keep everything together. As food was consumed, compression was so helpful.

        Great compression sack

        • Familiarity: I've used it several times

        I got the medium to make a sleeping bag more manageable and it works great. Instead of a big unwieldy blob we now have a neat compact package that takes up much less room. Very sturdy and great design.

        Sturdy Stuff Sack

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

        When you want to stuff stuff into stuff Id recommend this stuff sack. But, seriously, its a little heavier than some ultra lightweight competitors, but stronger/thicker materials than others as well. I like the exterior zipper pocket and feeling secure about the ripstop walls and stitching when you really crank down on the compression straps. The picture below is my 15 degree Big Agnes down sleeping bag rolled up WITH Therm-a-Rest style inflatable pad inside the medium size sack. Sorry I couldnt find any of my Nalgene bottles, but hopefully the Pringles give you perspective. I fully expect this sack to last for years.

        Sturdy Stuff Sack

        Good sack, does its job well

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

        Bought the Large compression sack for my sleeping bag. It does the job admirably, however, I do find that it is larger that it needs to be for the job. I am able to completely tighten the tension straps. This makes for a somewhat large sleeping bag. While completely serviceable, I do wish the sack was listed in litres on backcountry.com and not just in hight and diameter measurements.

        Love the straps

        • Familiarity: I've used it several times

        I love how sturdy the straps on these compression sacks are. I also have the Sea to Summit compression sacks which are great for cutting weight, but the straps are a pain to deal with. I can easily fit my 30 degree down bag in a size small.

        Great Piece of Gear to Have

        • Familiarity: I've used it several times

        I needed a compression sack for my down sleeping bad during an upcoming trip. This was the perfect option, durable, solid, compresses well and multi-functional. I felt that I could really crank down on the straps without feeling like I was going to break anything. I feel like there are a million uses for a compression sack if you are a big camper, and this a well-price, solid option.

        Unanswered Question

        I have an older edition (bought in 2013 I think) Mountain Hardwear Lamina 20. It's synthetic so it's heavier and bulkier but I was wondering which size would be good from these options and also if there's any risk in damaging the bag by using a compression sack like this?

        Unanswered Question

        Would the Alps Mountaineering Razor liner/bag be too small for the small? just curious because the sea to summit xs event sack is supposed to be perfect size?

        I have a 6'6" Kelty Ignite DriDown 20 sleeping bag. I'd like the smallest diameter compression sack that can work with this bag, do you think I could get away with a small compression sack or would I require a medium?

        I have a North Face Aleutian 20 Sleeping Bag. What size is recommended for my bag?

        Hey Ashley,



        So the The North Face Aleutian Sleeping Bag: 20 Degree Synthetic in a the regular version has a packed size of 9" x 17"



        This comes to be 1081.5 cubic inches or 17.75 liters.



        So for 17.75 liters, I'd suggest the M Liters for this stuff sack.



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

        Unanswered Question

        I have the womens 15dg solera mummy and im looking at getting a quality compression bag, it came with a large one but my sleeping bag rolling skills are pretty decent and i end up with way too much extra room. Anyone have a comparable bag or sizing opinion.

        What would be a good size for a standard sleeping bag?

        For most synthetic mummy bags I would go with a medium. For a synthetic semi-rectangular bag I would go with a large. For a down mummy I would go with a small. For a down semi-rectangular I would go with a medium. Lots of differences between bags though. Give me a shout and we can discuss further.

        I'm trying to compare this to other compression sacks, which have size listed by volume. Do you happen to have a liter size on these? (I think I may need to look at a size large).

        Thanks!

        What size would best fit a Kelty Cosmic 0 sleeping bag? I am getting ready to order the bag but it doesn't come with a compression sack(So I have read in the reviews.)
