I travel a few times a year for work and a few times a year for pleasure, so I thought I was a pretty good road warrior. These bags have really changed how I pack and made it a breeze to quickly pack and repack. You can neatly fold your clothes in the bags and they don't shift around in your luggage. The large cube can fit a few dress shirts without wrinkling them too much. I don't think there is anything out there that can prevent wrinkles though. The smallest cube is useful for socks and underwear. I own two sets which fit into my large rolling suitcase perfectly, with a suit or two and a shoe bag. After getting to where you are going, you can quickly unpack and reuse the empty bags as laundry bags to repack. By the end of your trip, assuming no additional clothing items were purchased, you are on the last set of clothes and everything is already repacked in the cubes to quickly throw into your luggage again.

For a long time I was using compression bags, but those wrinkle your clothes too much and only seem to make sense when traveling during the colder months where you need to bring outerwear that is bulky. I was wondering why people would rate these cubes so high, but using them, I can see why. For anyone who travels frequently, this cubes are a huge time saver. Buy two sets for a large roller - should easily fit enough clothes for 7 days.
