Fits in overhead and is large enough to actually bring some clothes and shoe options.  Love this and I have had many different bags.  I read the reviews on the wheels having issues, not being robust.  I have been using for 18 months and have seen no issues.  I am rough on my luggage and this works great.  The only better bag I have is a hard case Samsonite from 20 years ago.  The pockets are perfect for a computer - I no longer need to carry my backpack with me as well, it fits.  Only wish:  a water bottle holder.  My last Samsonite had one on the side and I miss it.
