Airlines like Ryanair, Wizz Air, EasyJet, Frontier, and Spirit charge for the space your bag takes, not the weight. Most check-in penalties happen because your soft items (jumpers, jackets, jeans) fill 60% of your carry-on with air. TravelVac removes the air. Roll your clothes into one of the three sealed bags, run the pump for 30 seconds, and 70% of the volume disappears. Same clothes, third of the space.
The cordless pump is USB-C rechargeable and the same size as a standard deodorant - it fits in your toiletry bag, not your suitcase. The bags are reusable PA/PE film designed remove oxygen, with high durability and flexibility, to seal hundreds of times without losing grip, so one kit replaces single-use packing cubes for years. No batteries to replace, no wires to detangle, no scrambling for hotel outlets.
