Fits perfectly in the overhead bin.  While others were being rejected due to Delta's pre-boarded bag size check and getting their bags checked for the flight, this Tumi fit perfectly in their size testing box (the reason I chose this model).

The bag itself is constructed of Tumi's signature ballistic nylon, so it should last decades even under heavy travel. There are plenty of compartments for all your things, an external bag holder to add a bag to this one while wheeling. There is a small suit bag that zippers in and out, though it doens't come with a hanger, one needs to purchase that separately. I would rather have the bag price increased and have that included then have to order separately after receiving the bag.  The wheels are fantastic and roll noticeably better than lesser luggage. I had no problems with the bag standing on its own when fully loaded with the expanding zippers undone. It did get tippy in that condition with an addtional bag hanging on the front. This was remedied by pacing said bag on top of this one.  The pull handle has worked flawlessly.

Overall another great product from Tumi, that I expect to have decades of use from.
