Mine was also "sticky" on the inside. I had an older black-and-green Vapor Trail that was sticky inside, also, I think all the earlier Vapor Trails, Virgas, and Nimbus Ozones used this fabric.
I took about 4" off my collar of my newer style Vapor Trail. I cut off the part with the drawstring intact and sewed it onto the lower part, much easier than redoing it.
I like the side pockets of the GG packs, just cut off the straps, they get in the way. You can put a LOT of stuff in them. I had to relearn some things with my ULA Circuit, because you can't put that much in their pockets w/o it falling out.
