Been wearing my pants on my rides to and from work. Most days I don't wear thermals under them, and my legs stay plenty warm down to about 25°F. I have to take back my suggestion to put stretchy material in the crotch. I've been wearing these pants back to back with my Dakar pants, and the reason I get cold in the Dakars is the crouch lets in cold air. Love the pants man. Look forward to seeing what else you have in store. Got some stickers so I can start pimping Dubinky?
