This excellent 21 inch by 14 inch weekend travel bag by Samsonite is made of very strong textured probably nylon fabric and has rarely (if ever) been used. It is unmarked and one of the internal straps has never been opened. 

Looking at the photos:-

The first one you can see the shoulder strap which will clip off and the two handles.
The second one shows the two handles clipped together. 
The third one shows the Samsonite label.
The fourth one shows the full width zipped top pocket.
The fifth one shows the hidden elasticated name label and the zip ends for the main compartment which can be locked together.
The sixth one shows the label pulled out on its elastic.
The seventh shows the bag opened with the floor mounted holding straps to tie down the contents.
The eight one shows the end pocket that is half depth and has no zip...it is the full width of the end.
The ninth one shows the other end pocket which goes from front to back full height and has has a side entry zip.
The last one shows the bottom which is a bit dusty from storage in the loft.

All the zips are intact, there are no marks on the fabric, the inside is clean in fact it looks as new everywhere. We were given a set and this one has never been needed. It comes from a smoke free home.
