Thoughtfully designed interior

A zipped panel on one half of the suitcase keeps your shoes and other items tucked away, while ballistic nylon compression straps and a cover panel with pockets keep your clothing compact on the other half. And generously sized, thoughtfully placed pockets maximize every inch of storage, meaning you can get more out of every trip. Pair with our Compressible Packing Cubes to take your packing to the next level.

    Great addition to my Monos collection!

    I was looking for a bag a little bigger than my Monos carry-on bag. This one is perfect. The only downside was that it only came in three colors so I couldn't get one to match my other bag. However, I purchased the navy and it is beautiful.

    Worked Good ...

    We used this luggage on a trip to Europe. On one of the 2 we purchased the handle broke before we even left. Monos has yet to replace it.

    The wheels performed "ok" ... not really better than others we've had. The locks worked as expected. We like the interiors very much - the zipper/compression areas that keep everything in place and the light color.

    Exterior scratched about the same as other brands of luggage.

    Great luggage & outstanding customer service

    I love my Monos check in bag!! I considered several others & decided to make my 1st Monos purchase. Shipping was quick & arrived earlier than expected. Packaging was simple & effective. They include a special “sponge like” eraser to help with marks. It works quite well. On my most recent flight, I had a layover and it was raining during that time. I had two checked bags and one was soaked inside and out. My Monos hard shell remained dry!

    The expandable option works so well for me and gives me much needed extra room. The interior has just the right amount of pockets. The compression straps are one of my favorite features as it really makes my bulky packing, flatten out. The only feature I wish they had is a handle or an indented spot at the bottom to grip.

    Be sure to register your product for your warranty. I had an issue due to baggage handling at the airport & my problem was taken care of immediately through customer service. I have never had such a quick and satisfying response from any customer service department. Love my Monos!

    Talking to a real person, privately, would have been nice

    The bags look very nice, I haven’t used them yet.

    I found it difficult to bypass the chat bot to talk to a real person when one of my bags was back ordered. I could not track it, either.

    I think you could do a better job of communicating with your customers in real time.
