Patagonia just reissued the 190 Black Hole Snow Roller double bag. I've had one for years, but when they started again this year, I picked up a second one. It's light, durable, and waterproof and has been great so far. Favorite thing is the tie down hooks. So now instead of a ski bag AND a rolling duffel, I can save weight by using a non-wheeled duffel, and just latching it on the Snow Roller and just pull one thing to/from airport, etc. The bag is pretty stiff for a soft sided bag and retains it shape well too. But looks like they're already sold out of some colors, and they only sell them every so often it seems.
