    Have questions about this product?

    Great for making room in a small pack!

      I bought this product to use while traveling across Europe for 3 weeks and wanted to make sure I had enough room for all my items. The product was slightly smaller than expected, but that is fine because I can use it for underwear, socks, etc. The materials are fine. I ordered the yellow and its a very bright color. The straps work good and securing and compressing all the items together. Overall, there is really nothing bad about the item. I have ordered some of the larger products (32L) and those work a lot better for shirts and pants!

      Great Bags

      • Familiarity: I've put it through the wringer

      Love these bags, I've used these on extended backpacking trips and island hopping with my family in the South Pacific. They make organization simple and satisfy my inner perfectionist.

      I took three of these into the Pasayten WA for a 6 day backpacking trip - I had one for clean clothes, one for dirty and another for jackets, etc. They kept the tent organized and my sanity in tack. My family and I used them for a 20 day trip to Fiji and surrounding islands – each kid had their own, it kept everyone’s clothes separated and organized. Highly recommended for families.

      Pros:
      - Satisfies your inner OCD
      - Light weight, well-constructed
      - Compresses well, though the smaller size bags only have two straps so your stuff bulges out of the middle (FWP)

      Cons:
      - The shape is a little off... I assume they built them with rounded corners so they would slot into a backpack but it makes loading them with folded clothing awkward. You can never get the clothes in them just right and you're left with some dead space on the corners.
      - Not enough colors (please make more colors!!!) – seems petty but with four young kids, it was a pain trying to keep track of whose bag was whose… would have loved to have a color for each family member.

      Hey Eric, Thanks for the review. The shape is specifically designed for stuffing into the bottom sleeping bag compartment of your pack vs packing clothes in a suitcase... you will see Osprey go in that direction too, just wait!

      Thanks for writing!

      Well built, great design!

      • Familiarity: I've put it through the wringer

      I have been using 3 of the 24l sacks for about a year now. Great product! These have 3 compression straps and evenly compress the contents. I use one for my sleeping bag and pad and sleep clothes, one for my tent and groundcloth, and one for my clothes. I like the straightjacket style because the bag is still the same length as my Cooke Custom Sewing Pioneer canoeing pack is wide, so it uses its interior space efficiently. I plan on getting 3 more of the larger ones for the larger pack I have.

      The person who rated this two stars needs to get some more outdoor experience but perhaps the 12l size could use a 3rd strap as well. I also find as another reviewer noted that these are so well made and airtight that leaving the zipper open a crack while compressing is needed. Maybe running the zipper 'around the corner' a tad might make it easier to fully zip after compression.

      • Familiarity: I've put it through the wringer

      I've been using the 32L compression sacks for traveling and have to say they have really helped keep my gear organized when traveling. I use two of the 32L to organize my outwear and regular clothes which helps me quickly identify where items are. I always hated digging for that illusive piece of clothing while rummaging through a gear bag because you end up unfolding everything in the process. Compression is easy and I found that if you leave the zipper open just a tad it simplifies the removal of air when packing. When done compressing and tightening the straps, I close the zipper all the way (it's a little tricky but not difficult). I let my wife use them on a recent trip and she was happy at how easily we could organize the kids clothing and ours. The 32L fit right into my Patagonia duffel too.

      Well built, poor design.

      • Familiarity: I've used it several times

      I've used this compression sack for a couple overnight backpacking trips so far, and it leaves a little to be desired.
      It's well built, and I think it will stand a pretty good beating, while being light, but it just doesn't compress your items very well.

      It's zipper design, means you can't really fill the bag to its full potential, and a corner always seems to be empty. Additionally I always get some fabric caught in the zipper. I wouldn't try and put a sleeping bag in it, because their light wight fabric might get caught and rip.

      compression is also not as efficient as with a traditional pill compression sack. It seems to ballon out between the sparse straps, leading to a larger than necessary package (see image).

      I have compression sacks for clothing, tents and sleeping bags, to get them small enough for longer trips. This sack although well built and light, just doesn't do the trick compared with a traditional design.

      Well built, poor design.

      Sean, thanks for the review. We always look at our designs critically, and seek to improve them as we go forward. I see what you are saying, but I do have to tell you that for the lower "sleeping bag" compartment in packs, this product shines. Thank you again for the feedback - good critiques help us make better product.
