Wolfman has a new tank bag. It's not on their website yet but I saw it at Bike Night at Beemers-and-More.
I think they call it the Rainer model. It's a modification of the Denali with skinnier side pockets like the Explorer and other improvements. Improved mounting straps. Designed for the F800GS, and other bikes. If I didn't already have a Denali I would be getting the Ranier. I've had an Explorer on my KLR for five years abd think it is excellent.
