Premium Space Saver Bags, Hibag Pack of 6 Vacuum Compression Bags (2 X Small, 2 X Medium, 2 X Large) with 2 Free Roll Up Bags no Vacuum Needed and 1 Free Hand-Pump, Saving more 80% Storage S (6-combo)

The bags cannot be used in carry-on luggage, for air travel, w/o TSA pulling your bag off the line for inspection. More than one TSA employee has described the compressed bag as "a large, solid mass", when undergoing screening. Huge disappointment since saving space in my carry-on is the primary reason I purchased the compression bags.
