Reviews Summary
Customers say this suitcase glides effortlessly through airports with smooth-rolling wheels. Many reviews mention the thoughtful interior design with effective compression panels and organized compartments. The expandable feature provides valuable extra space when needed. Users appreciate the lightweight yet sturdy construction and find it spacious enough for week-long trips. While most praise its maneuverability and capacity, a few note it's slightly smaller than expected when not expanded.

    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.

    A concern

    The carryon looks great! I have not used it yet. The color is beautiful. I took a star off just to ask a question: I see quite a few people complaning that when full and compressed the trolly handles wont slide. I can see how compressing that side of the carryon will push down (bend) the casing of the trolly handles. Do you have a fix for this problem?

    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.
