1. Fit two weeks in a carry-on - the lid closes first try.
You know the move: knee on the suitcase, both hands on the zipper, praying. Here's what actually fills your bag: air. The Pro's 27-liter bag swallows about 15 days of clothes, then the pump pulls the air out and it shrinks by up to 70%. Jackets, jeans, hoodies - gone flat. Same carry-on you already own, 3x the room. The lid just… closes.
