ALPS Mountaineering Cyclone Compression Sack
Compression sacks save pack space, but their spherical shapes often make them nearly impossible to pack. Alps Mountaineering cures this annoying problem with the Cyclone Compression Sack. Wraparound straps compress the Cylcone into a long, skinny, and easily packable shapeŚmore like a cylinder than a bulky nylon bowling ball. *Please note that the photo shows three bags, but they're sold individually.

The sacks worked great for compressing a synthetic bag way smaller than I thought it could. I do wish there was one more additional strap to vertically compress but other than that they work great. I got a medium for one of my larger synthetic bags and it shrunk nicely. I also ordered a large size (that truly is large) but I havent used it yet. Seem to be super durable.
Love this concept: ability to make either soccer ball or long
Love this concept: ability to make either soccer ball or long tube shape to suit available backpack space. But can't find weight anywhere. Anyone know?

I have always grappled with the problem of classic stuff sacks: when compressed, they are approximately the shape of a bag of potatoes. For those of you that are sick of trying to pack a sleeping bag/clothing into a thin space (Like into a 65 liter pack which already has a water reservoir and a tent in it), then this sack is for you. The wraparound straps are fantastic, and easy to use. I have owned cheap Wal-Mart versions of this and torn the straps off them all. The Alps sack is of good construction.
No, it is water resistant but far from water proof.

I'm able to fit my Big Agnes Lost Ranger bag into the medium, and without really leaning on the straps, I'm able to get it down to roughly 70% of the BA Stuff Sack with the Girdle. The lower bag is the BA Lost Ranger, the middle is a Dualcore pad, and the top is a fleece liner.
Which size would fit a Sierra Designs Women's Glow 15? The stuff sack that came with it is 9x19.

Liked it while it lasted

It compresses bags very narrow and you can really crank down the belly straps. My problem was by the logo that sits on the little flap that covers the mouth. That flap ripped when I tightened the strap that connects the mouth and base. I might have tightened it too much, but once you get a little rip, you can't really help but have that seam open up. Thankfully, Backcountry's awesome 100% guarantee covered my ace.

This bag works fairly well. You can't stuff as much in it as you can the top compressed bags, but it keeps the bag narrow, instead of a ball like the top compression sacks. Works well inside a backpack when you want to stuff something next to it. It all depends on what you need it for.
