Since I seem to have the only pouch in captivity at the moment, here goes.
There are two main parts to the pouch and on mine they are coded as green and black. Only the green is Neoprene, the black is a high grade industrial nylon sometimes called “rip-stop.”
The green Neoprene is not lined and is used to form the pocket for the Reader. The top edge of the green Neoprene is finished in binding tape to avoid fraying with constant use. It has a little give that produces a snug but not tight fit. It would stretch more if required; but, more force would be needed to insert and remove whatever was put there. It also is a bit compressible and provides additional protection that way.
The black nylon comprises the back and the flap. On the back there is a little padding – not enough to trust the screen to. The same type of minimal padding is also on the top edge that folds over the Reader. The flap is reinforced with a sturdy but flexible board somewhat akin to what is in the original Sony standard case. It does not feel like it is the rigid plastic that M-Edge talks about in some of their cases.
If you order a pouch to just take the Reader without the case then you must make sure that it is always inserted so the screen faces the flap. That will give it much more protection than the original case did. Reverse it so the screen faces the back of the pouch and it has less protection than provided by the original case.
Placing the Reader in the pouch in either the standard case or the leather case greatly increases the protection to the screen.
Now as to Duke’s question about dropping the Reader from 5’, send me your Reader and I will test it.
