Amazing sleeping bag shrinking gizmo.
Lightweight, sturdy, well constructed and folds up into a tiny disk when not in use. Half the compression straps have quick release clips, makes decompressing two clicks quick. A Helium 1 (smallest version) will compress a Big Agnes Cross Mountain Long into a 6x13.5 inch torpedo. Likewise a Big Agnes Lost Dog Long together with a Sea to Summit Reactor Thermolite Liner shrink into a 6x9 inch football. I’m buying a second Outdoor Research Helium Compression Stuff Sack (1) so that both my sleeping bags and liners will fit where only one fit before. Altrec has quick tracked shipping and easy returns. Buy here!

The Helium Compression Stuff Sack works very well.
If you do much long distance traveling for hunting, fishing, etc., you know how frustrating it is to attempt to take everything you need on a commercial airplane. Because of baggage weight and size restrictions, I was never able to take my sleeping bag. The Helium Compression Stuff Sack has made it possible for me to take a bulky sleeping bag on board as a carry on in a compact package. I purchased a size 4 sack. I found that I was able to compress a standard size rectangular bag filled with 2 pounds of down, having a total weight of 3.7 pounds fairly easily. The compressed size is easily handled and fits aircraft storage compartments, even small ones with no problems.

Perfect compression
Perfect compression not only for storage but as you carry your sleeping bag along. The #5 holds well 1 sleeping bag and shrinks it to amazingly less than half its size. Best buy!

A little work but a great product
I'll be the first to admit, my swiss army protactor/ruler combo eyeballs have a bit of a problem accurately sizing things up. Needless to say I purchased the medium (#4) when I needed the larger sack for my sleeping bag. With a little bit of coaxing my bag has never been more compact (and dry, too). Great choice for anyone dealing with space issues on the trail.

Indespensible
I have two problems with packing that compression sacks solve. First - I never seem to have enough room in my pack to carry everything I want/need to bring with me. Second - Everytime I unpack/repack, I have what seems like innumerous loose items that need to be placed back in the pack which is laborious. Compression sacks solve both problems well. They keep similar soft gear items organized and compressed into the smallest possible space to maximize the available volume in your pack

Great Compression sack
Shrinks my down sleeping bag to a very small size. The only thing that makes me nervous is that it the seams look as if they have a lot of stress on them when the sack is fully compressed. Overall, great product.

Great Product
Works great. There are enough straps to compress anything. My only complaints are that the inner sleeve is not adjustable (I guess you could always buy a few different sizes) and that there are no straps going perpindicular to "thin" things out as you are compressing downward. Other than that, it is a great product of high-quality construction.
