Great packing cubes. Main zipper is easy to use but you have to be careful with the compressing one since it has a tendency to catch on the material. The sizing for this set is much more practical for my usual travel (compared to the larger set since I don't need a huge bag). Great for carry ons!
I purchased these to travel around Europe switching hotels night to night but with one suitcase. I packed each bag with a set of clothes and instead of rolling my luggage in nightly, just grabbed one bag per night and left the heavy suitcase in the car. These are lightweight, and if you roll your clothes, can easily fit pants, shirt, and a jacket in the larger pouches. The smallest bag will fit clothes as mentioned, but it is somewhat a tight fit. Zipper and material are decent material, seem like they will hold up for a while.
Design of the zipper causes it to frequently get hung on the fabric that's bunching up with the compression (something other compression cubes don't do). The cubes also don't open all the way, making it harder to pack and to see what clothes are in them after you've arrived at your destination
I got these to help me pack as much as I could in a single suitcase for Iceland. I was disappointed to realize that the zippers only went about a third of the way around, so it was harder to access the first items added to the bag. I also found that while they did compress, they were still a bit bulky in the middle. In the end really didn't save much room in the suitcase. I ended up using the super large air compress bags with more success.
I'm able to pack so much more!!! On top of making my clothes more compact, I'm able to keep everything in my suitcase more organized AND I purchased a different color for each member of my family. I feel so organized.
