I used this to travel to Spain for 6 weeks. I wanted something that would get my gear over there without having a mess of ironing to do. I did not pack anything overly wrinkle prone, but did pack khakis, jeans, t-shirts, and cotton blouses. They came out great and I had no trouble finding my clothes because they were organized by type, ie. undergarments, tops, bottoms, etc. I also did not have a mess from the TSA people when they went through my bag.
The one thing I would change about them is that they be a bit deeper. I have two sets of these and I was able to pack 6 sets of summer clothes and some extras for cold weather in them.
This is the second time I've bought these packers. Only because my husband started using them too, and hence we need more. It's the only way to travel and keep everything organized, folded and looking nice and clean.
This is my second set. They help keep my suitcase contents compact and in place. The large one works for shorts; the medium for t-shirts; and the small for underwear. It makes packind and unpacking very easy.
