what about cold/freezing rain pants? I've got everything else waterproofed and am dry except for my legs which are frozen when it rains cold. Hell, it's snowing now but melting just before it hits the ground and it'll be like that for my morning commute tomorrow. sigh. The only rain-resistant pants I see at my lbs are about $120. I don't need specific brands but what are the kind of pants I need called? (i.e for rain/wind you need a waterproof outer shell)
