I been needing cap carrier all my life, so perfect for hats. I used it on a daily basis and you can get about 7 or 8 hats in it

This Cap Carrier is Great size, vibrant color, very well built. Thought it would take up too much space in my luggage, but it is such a great size. Perfect fit and a great investment! Highly recommend.

Bought this hat case for traveling so my hats don’t get smashed. Fits three hats comfortably. Seems small enough to put in a suitcase without taking up too much room. It also comes with hooks that you could probably hook it on to your carry on/backpack. Case has a hard shell too, so it seems pretty durable.
