At first glance this sash looks cheaply made, like it's nothing but thin polyethylene.  It has the feel of plastic, not a true woven nylon.  The trim around the edge is definitely cheap fabric backed plastic and a very poor imitation of leather.  It seems like it's going to fall apart with regular use like it's going to crack and tear.  I don't know if I want to keep it.  I'll try it out around town to see if I want to take it on a longer trip.
