It is the one. The best luggage for me at this point. The brand? MONOS!!! The best investment for your money.

See that? I overpacked it for 22 days, as evidenced by the bulge, and rolled for kilometers. My boyfriend dragged it because I’m a travel princess. LOL. And I kid you not, he pulled it carelessly and dragged it down the stairs each time we moved from one place to another.
This luggage was not only in the carry-on, but we also used it for check-in. And we all know that check-in luggage is treated badly. It didn’t have a great time in taxis and trains, but it held up so well.
Although this is not cheap compared to other luggage brands, it is not as expensive as Rimowa and it is worth every penny. Just choose a color that does not easily get dirty.
