It was in the high 40s, low 50s last night - my first ride in the Firewalls and the wind was blowing 15 - 20 mph. I checked our local wind site because my time was slower than usual.

Anyway... I was really comfy in the Firewalls. The biggest part of my calf - oh my god I just measured it - 16.5 inches with jeans on! 16 inches if I pull it really snug and the mediums were fine on my colossal calves.
