I am commuting from home to my SAT class by bike this summer. It is about 3-4 miles away, and it takes me about 20-25 minutes to get there. Initially after stepping off my bike, I feel fine and pretty dry, but after sitting in my seat in the classroom, the sweat comes pouring down. Is there a way for me to lessen the sweat? Cause I don't like looking like a drowned molerat. I could go slower, but that would still make me sweat.
