there are many rides where i swear i'm not sweating at all, but when i smell my clothes afterward...guess what? they stink. so, i'm sweating more than i realize.

i wear wind breaker style pants over normal cycling shorts in the winter. this tends to make my legs sweat quite a bit and usually my shorts are pretty damp with sweat when i take them off after the ride. i just never notice any sweat on my exposed skin (usually just my face).
