helps much more than expected
These packing cubes or zip-bags have made a much bigger difference in my travel packing than expected. When I travel, keeping track of where I put which item becomes impossible. Who has time to keep the suitcase in order over a week of on-the-go travel? There's so much more fun and important stuff going on!

So, I've found that being able to think: okay, all the big clothes are in this bag, the smaller ones in this bag, and my extra little things that usually end up rattling around in the bottom of the suitcase where I can't see them are all in the smaller cube (e.g., hairbrush, travel alarm, phone charger, camera charger). Sometimes I wish the cubes weren't black, because this makes contrast bad in dim light, but black has its pluses too.

They do their job, and are not as heavy as others...
The nicest things about these cubes are that they are lighter than the Eagle Creek ones, and that they sort of have a springy memory to their size. I try to pack light, I don't want my packing aids to add considerable weight to my backpack. These are the best of the lot, IMO, better than those from Eagle Creek and Magellan's, in functionality, size, and weight. I've given several sets away as gifts as well.

Great for a backpacking trip!
They held a lot and made picking clothes out of my bag really easy everyday! Everyone else's bags were a mess, but I knew I could always find my underwear in less than a minute! It also made separating my dirty and clean clothes idiot proof.. A great buy.

Never leave home without them
What can I say? I've had these for a year now and they go everywhere I do. I'm an American living in Europe and travel every chance I get. Most of my trips are 4-5 days but I have done several one week trips as well. I've only actually ever used the large packing cube once...and that was for a snowboarding trip to Switzerland. I was able to fit all my gear...boarding pants, jacket, thermals, 2 pair of gloves, 2 hats, 2 pair of socks, and goggles...in the large cube and everything else in the small ones. I only ever use the small cubes for regular travel. If I can't fit everything for 4-5 days in those two cubes, I'm bringing too much. I spent 8 days in London and Paris with just the two small cubes and they were perfect.

It's amazing how much fits in there! Just roll it all up tightly and you can fit plenty. This was another one of those products that my husband thought I was silly for buying (that seems to happen a lot). I finally bought him his own set when I got tired of him trying to steal mine :)

The cubes are black mesh on the top and sides and solid black (nylon?) on the bottom. While I wouldn't call the mesh "stretchy" it does have some give to it so you can cram that last t-shirt in there. The zipper is strong...I've packed these things to the max for at least one trip every month for over a year and have never had the zipper split. It's also great when you're trying to get that one thing out of the bottom of your bag and have to pull everything out to get to it...you're not having to pull out socks and underwear for the entire airport to see.

No more compression bags
In the past, I've used compression bags to organize my clothing when traveling. I decided to give these packing cubes a try since my compression bags were on their last breathe. I am very happy with my purchase and will not be going back to those bulky plastic bags.
The little cubes stored much more than I thought they could - I was able to pack 2 weeks worth of underwear (tops and bottoms) and socks! My only (small) complaint is I wish the set came with 2 large cubes instead of just the one. I ended up getting the eBags Large Packing Cubes - 3pc Set for the rest of my clothes.
