Two bags in one shell is why this sits at the top of our list. Zipped flat, the WALNEW measures 16.1 by 8.3 by 11 inches, and we slid it under the seat in front of us without a second thought at the gate. Unzip the base and it gains 4.7 inches of depth, which is what saves the trip home when the outbound packing was optimistic.
The 35-liter shell is waterproof polyester, and the layout is the part we kept appreciating: seven compartments, a lined pocket for wet things that we used for a damp swimsuit, and enough exterior pockets that a passport and phone never meant digging. The shoulder strap unclips when you want to carry it by the webbing handles instead.
Nothing about it is rigid. Packed halfway, ours slumped into a soft pile, which is exactly what lets it squeeze into a tight underseat gap and exactly why we pack it in cubes. The expansion is the other trade-off: open the base and the bag is 15.7 inches tall, taller than the space at your feet, so the extra room is for the overhead bin or the trunk of a car, not for boarding.
WALNEW rates it machine washable, and the fabric wiped clean when a bottle leaked on the way home. For a two- to four-day trip where you're carrying one bag and want it to stay legal, this is the one we point people to.
Pros
- Fits under the seat as packed
- Zip-out base adds 4.7 inches of depth
- Seven compartments including a wet pocket
- Waterproof shell, machine washable
Cons
- Too tall for underseat use once expanded
Our default pick: underseat-legal as packed, expandable for the trip home, with the pockets and wet storage a real trip needs.
