Brighton doesn't open until tomorrow, so I haven't had a chance yet to try these pants in the snow. I'm sure when I do though, they'll be great.
I bought the Chocolate Tweed pair and love them! They fit really well and like all 686 gear, they have all the bells and whistles (lots of pockets, zip in lining, a tool etc.) I don't plan on using the lining, and think that they'd be plenty warm either way as they are a bit on the heavier side.
