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.

  • Horizontal and vertical compression straps
  • Double stitched seams

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.

Unanswered Question

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

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.
