I use the air compression bags from BB&B, no vacuum required. I ONLY use them for our dirty laundry tho for the return trip home. They help make room in the luggage for souvies & such...but FOR ME they wrinkle stuff up too much to use on my clean, freshly ironed stuff. Also, note that they hold a lot but they can get really heavy, really fast so allow for that if you're flying and you're trying to stay under 50 Lbs!!
