I have the exact same pants. Energizer bunnies, with some new cordura armor courtesy of Patagonia's warranty dept.
I also have some Flylow pants courtesy of the raffle at the San Francisco showing of Hand Cut. They were XLs, but Dan exchanged them for mediums. Pretty sure they're the Chemical pants. They're the only "ski pants" I've ever seen that compare to Patagonia's Primos. Burly as shit. They have inner and outer thigh vents too, so they'll be great for touring if you want a do-it-all pant.
I'm 6'1" 165 (32x32), and the medium fits me well. They're reasonably baggy to begin with.
