Eagle Creek Doubleback 22, Smokey Blue, One Size Versatility and ultra-durable construction. Reinforced hypalon material blocking, bumper, and kick plate protection Oversized treaded wheels with protective wheel housing Hubby is buying this for our next overseas trip, so don't know how it really compares. I still have mine (dark red, grey, black) from 10 years ago... love, love it. Zippers are great, wheels have worn down just a bit. It was expensive, but worth every penny. -Grahm
