    Cyclone Compression Sack

    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.

    • Stuff sack offers low-bulk packing wherever you roam
    • Ultralight ripstop with double-stitched seams for durability
    • Three straps compress diameter
    • Item #ALM000J

    Contains and protects my sleeping pad.

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

    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.

    Only width compression works

    • Familiarity: I've used it several times

    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

    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.

      Pretty rad

      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.

      Pretty rad
      Unanswered Question

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

      Unanswered Question

      I have a Crescent Lake zero degree Alps Mountaineering regular sized sleeping bag. What size compression sack should I order for this?
