Save space, travel further.

Compression sacks save pack space, but sometimes they're still a little bulky and awkward; Alps Mountaineering added horizontal compression straps to the Cyclone Compression Sack to make sure it packs down in all directions. Bar-tacked stress points and double-stitched seams ensure that this sack can take years of use and abuse.

The XL cyclone compression sack worked out even better than I had hoped for my Wilderness Technology self-inflating sleeping pad. The pad is great but only flaw is it swells a bit after rolling it up, closing the valves and placing the elastic bands around it. This swelling contributed to the ripping of the cheap stuff sack that came with it. After a few years of just throwing it naked into the back of my truck I came across this Alps Mountaineering compression sack. It is as if the sack was made for my sleeping pad. The XL is the perfect size for it to slide in easily, the horizontal compression straps assist with the swelling issue and the vertical strap lets me lock down the lid to the bag after cinching it closed. The material is great, not too thin or thick and feels durable. Could not be happier.

the medium is list as 8x19x10
I assume that is the uncompressed size. What would it compress to if full of clothes

Only width compression works

Maybe I'm the only one with this issue but the single vertical strap is useless. It's compression capabilities end before it really gets even close to tight. The three side straps do a great job. Just not the total compression I was looking for. Good quality otherwise though

I also had this issue. They definitely weren't the type of compression sack I was looking for. I returned them as I needed vertical compression.

Same issue. The length cuts off the compression too early. It should compress by about 5 or more inches length-wise, but it's not designed to do that. Now I have to get another compression sack.

Good Sack

Compressed my bag. Pretty impressive.

Overall a good compression sack

    My sleeping bag fits nicely into the bag, but I like fitting my sleeping bags tight in the sack (nothing against the comp sack).
    I will definitely still use this sack for other stuff though.

    Bought this for my dad, it scrunched his mammoth rectangular Coleman sleeping bag down to an acceptable size when packing up for a trip. It has three straps goin down the length of the bag and one vertical strap. If it had two verticals straps I'd given it 5 stars. Picture compares the large green compression bag to the extra large orange cyclone compression bag.
