This is a great looking bag, at a good price, that will fit in all airline overhead bins, even the narrowest of only 10 in. It is made from Koskin which is a synthetic soft, flexible leather of the type used in many purses and other products. The bag has one large compartment and one large side pocket. The extendable, attached, handle used to wheel the bag is concealed in its own zippered compartment. This product has one flaw that I found bothersome but I was able to find a simple remedy.The flaw is that when the handle is in the extended position the bag will not stand up by itself, even though it has two wheels and two non rotating plastic skids, the base holding the wheels and skids is flexible enough that the bag will fall over regardless of whether it is full or empty. I believe that the base holding the wheels and skids is purposely made flexible so that the 12 in. high bag can be squeezed into 10 in. high overhead compartments. If the side holding the wheels was rigidly connected to the bottom of the bag this would not be possible. This flaw is inconvenient and annoying at ticket counters etc.My solution was to take a rigid shelf bracket, short side of 5 1/2 in. and long side 10 in. and attach it to the track in the base of the bag. There is already a screw that can be used at the end near the wheels and at the other end I used some vinyl tape to attach the bracket to the metal track. The whole simple modification is concealed by the inner zippered lining already in the bag.Voila! The bag now stands up by itself both when empty and full. Because my rigid shelf bracket is only 5 1/2 in tall the bag leans a little when it is standing up but the 12 in. high bag can still be squeezed into a 10 in. high compartment when necessary.
