Carry-On Flex 行李箱（

This thing fit perfectly in the overhead bin on a Spirit flight, which was a huge relief. The expandable zipper gave me just enough room to squeeze in a bulky hoodie at the last minute.

The expansion zipper added a solid two inches of space when I packed souvenirs, and the handle felt very sturdy rolling through the airport. It still fit easily in the overhead bin on a crowded regional jet.

Flew three times in two weeks and never once worried about overhead bin space since it's sized to fit overh—the wraparound zipper gave me room for a bulky souvenir jacket I bought last-minute. The zipper itself glides smoothly too, no snagging even when packed tight.
