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.

    Monos Expandable Check-In Medium and Expandable Carry-On

    The luggage is really nice but I was upset that when I bought this piece and the expandable carry on piece on July 5th there was a 20% off, but when I saw it in the cart it was less than 20%. I wrote a note to Monos but they said there are exceptions to the sale. I think it is very misleading.

    Beautiful and Useful!

    The carry-on is a beautiful, one of the largest, to obey most of the size guidelines and it is smartly designed. I couldn't keep it - little on a heavier side, and we needed a lightest possible carry-on for our adventure travel. But for a normal travel conditions I would love it. MONOS, please, come up with a light version! I would definitely get it.

    New Expandable Carry-On

    I love the new expandable carry-on. It’s a great alternative when I need a little more room but don’t need the larger check in. That said, I would have given it a 5 but the zipper on the expandable section hangs up and doesn’t work as smoothly as the other zipper.

    Great luggage!

    I was a little hesitant to get the pro because I read reviews that you get less internal space with the zippered front pouch but I’m sitting at the airport right now for a weekender and I am loving this bag! I have already received compliments (Ocean Blue is beautiful) and although it appears you don’t have a lot of room on that side of the suitcase I was pleasantly surprised at how useful the room was. I packed al of my clothes and shoes on the opposite side of the pocket and I was able to put toiletries and such on the pouch side! It’s still less than a piece without the front pocket but I’m finding it works quite well!

    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.
