Great compression and organization
I also reviewed the other size of these compression cubes. I can't tell which size is which - I found the larger cubes more useful, though. The smallest size one didn't really fit as much. But the large and medium fit a lot of clothes and made it really easy to pack and unpack in multiple locations! You just take out the cubes, unzip the compression part, and put them on your hotel room shelves or in drawers. You don't actually have to unpack everything! As clothes got dirty, I could make one cube a 'laundry bag' and keep the other clothes clean. They're totally worth it if you're traveling to multiple hotels/locations in one trip and if you're trying to pack small.
Great, but wish they had the ability to label
I have both the newer and older version. On the plus side, the mesh allows to air things out. I do miss a feature from the old version, which had a little pocket to slide in a tag/label so you could list the items in each bag. Since the old ones have lasted for many trips, this is not a big deal but I do miss it on the new ones.
Great for keeping packs organized
I love these expanding packing cubes - I never really used them until now and just stuffed items into my pack or bag. They are incredibly lightweight and can be kept smaller or zipped out for more space. Made for very easy access to clothes during our trip. One thing to note is they have a mesh side and while I liked the peekaboo window to see my stuff I worried that if there were a spill in my bag the cubes would not keep my clothes dry. That said, they hold a lot! Not as easily condensed as a stuff sack but very useful.
Well Designed Packing Cubes
These cubes have great design features. They are the perfect shape to pack your folded clothes and have a mesh opening to allow them to breathe. They come in two different colors which helps to distinguish which one you are grabbing in your bag. And the best part is the zipper on each that lets you expand the cube to twice its size. They then open up to let you pack in a lot! I have used other cubes before, but these were a much better and more useful product due to how they were designed. And I just love the blue color they are made of!
Can't recommend these enough
I was able to fit a eight days worth of "nicer" blouses/tops for evening into the large cube, and a week's worth of workout clothing into the medium one -- shocking, as I am not a small person. The cubes are sturdy, and kept my bag well-organized.
Failed immediately.
I purchased this for a trip to Patagonia. After a very long day of travel I opened my pack to find my large organizer had come apart at the zipper seam. Not a huge blow to my adventure, but a disappointment for sure. I’ll be returning it for a replacement. If REI stands behind it, I’ll recommend, but hopefully the replacement doesn’t fail.
Great design and good workmanship UNTIL...
Great design and good workmanship UNTIL... the mesh coating started flaking with tiny pieces all over everything . Unfortunately started 13 months after purchase. Too bad since all the other materials and zipper are holding up well.
Packing cubes keep clothes organized
I discovered REI packing cubes years ago and they make travel so much easier by keeping clothes organized in the suitcase. In hotels and cruise ships, I just pull the cubes out of the suitcase and lay them on the shelf or in the drawer. I ordered these because I needed a few more. When travelling to cool/cold locations, I bring more layers so I need more cubes. These are a good size (med & large) for sweaters, shirts, jackets, and pants. They also expand 3" so I have more flexibility in how to use them.
So much space!
I just took a trip up to the Oregon Coast and packed these. They were wonderful and spacious. I could fit everything I needed and it helped me feel organized with all of my belongings. The only feedback I would provide is the mesh can get caught on things.
Poor quality
The new packing cube is not good as the old packing cubes. The new one looks cheaply done and not that durable as the old one. The new one is similar to the one I bought at Walmart Please bring back the old Rei expandable packing cubes
