The bag is really well made and the materials are well chosen. Unfortunately, the design does not fit perfectly to the Surface Pro 3: Type Cover with the device can be very difficult to stow away in your pocket, because cover and bag produce too much friction. Is still the hand strap for the Surface pen attached to the Type Cover, is almost nothing, since it is wedged again. This brings us already to the last point, because a hand strap for the pin not found also on the pocket. Anyone who wants to transport the SP3 without Type Cover, is well served by the bag, but that will probably be the least. Use more recently, "Maroo Leather Sleeve with magnetic front flap for Microsoft Surface Pro 3 brown / black" and was better here thought along. The tablet also fits with keyboard loose in the pocket and for the pen is a matching strap on the inner edge available.
