I have a gently used Gorilla 40 pack, and the size is a medium. I paid $235 for this pack about 8 months ago. I also have a ZPacks size medium Cuben Fiber pack cover, and I paid $50 for the cover about 8 months ago. This pack only has 40 miles on it, and 1 night of use. There is absolutely nothing wrong with either of these items, and look as if they're new. We're down sizing our gear closet, and are getting rid of a lot of stuff. Since both of these items are practically new I'm going to ask $200 for both items, and I'll pick up the shipping.
