Scott's backpack was one of the older gateway backpacks...
My friends original Gateway Backpack has withstood many years of punishment. His wife offered to buy him a new Revolution bag and he said there wasn't any reason to switch. (Of course she bought herself the new Rev bag instead).
I've been using a PDGA bag for 4 years, but I finally lost the last set of zippers and most the other straps besides the main ones have long since came off. I'm also not sure what I'm going to replace it with.
