i see no point in it as a commuter.
it's just silly to put on an outfit to ride, get sweaty anyway, put on another outfit for work ect.
I'm not sure why people are so scared to sweat.... it keeps your ass cool.
Nothing is better than being sweaty and stopping at a light and letting it run down you, then take off and let the wind run through it. That's staying cool.
Where I work I can wear what I want though so I just come in with shorts and a t-shirt.
No probs.
