a must have for traveling or camping!

I am using this on an old sleeping bag, it does a great job of compressing it and has made transport of the sleeping bag a total breeze!

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

I bought these to use on my motorcycle adventures. The do work but I've found that they are a bit heavy and bulky for my use. I've gone with another brand even though they cost more

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.

fits my Marmot Col Sleeping Bag: -20 Degree Down perfectly and really makes a huge difference when packing for trips. perfection

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.

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.
