We are traveling internationally and decided to go with one checked bag between two of us. This allows us both to compress our clothing into smaller, more manageable packages. Packing the TravelPack correctly is necessary as you want to fit it into your baggage in the correct spot before packing. The removal of air just makes it smaller, NOT lighter. The added plus is that it is waterproof. So, if your baggage is left out in the rain by baggage loaders, your clothing will not get wet. The vacuum provided certainly is powerful, small, and easily rechargeable. This is a wonderful addition to travel.
