Our gliders have made peep holes in all 4 of their pouches! :-S I'm not sure why they do it but they like sticking their noses out of them!

Do you see this as a problem as per your post above?
I made a bag with snooker table lining and normal fabric on the outside. Stuffed it with toy stuffing to make it cosey, and threaded cord through the one half and tied it to the bars of the cage with a double bow, and they sleep with the bow inside the bag, it's like they are making sure I wont take it away from them. But because it is tough fabric they haven't yet managed to make holes in it. & they never chew it. I do check regular though. If you would like to make one you can buy off cuts of both fabrics from market stalls very cheap. BAT FINK:
