Monos Carry-On review

The Monos Carry-On gets the basics right for the overhead bin. Monos lists the exterior at 22 x 14 x 9 inches with wheels and fixed handles included, which is the same limit Travelpro's size table shows for American, Delta and United, so you are not relying on a sizer being lenient. The shell is polycarbonate, and the bag weighs 6.60 lb with 39.9 L of space. Inside, a zipped panel covers one half and a compression pad with nylon straps holds the other, and Monos includes a laundry bag, two shoe bags and a luggage tag. The handle is a custom aluminum design with the release button underneath, and the lock is TSA-accepted. Every Carry-On has a limited lifetime warranty and a 100-day trial; a paid Lifetime Warranty+ adds airline damage and lost luggage cover. The trade-off is space: there is no expansion zipper, so you get 39.9 L and no more.
