First, let me say that I have read the other reviews and some of them are just wrong. This briefcase is leather. Of course it is cowhide so it is a little stiff, but it is extremely durable. Second, the top flap does indeed stay open with no problem. The briefcase is very attractive and functional with all the pockets and slots. My laptop fits with room to spare. Regarding the weight, the briefcase is sturdy and made for years of use. If you want a light weight case, buy a fabric or vinyl one. Finally, the price is right. I saw a briefcase in a retail store that I loved; however, the **** price was out of the question. This briefcase will do the job and look good doing it.
