>>2073076total, whole body air-cooling has some good effect on swampass. no shirt, no helmet, sandals no socks, basketball shorts and cotton boxers give best air circulation. you can carry a shirt if you need one for your destination. I also carry washcloths for sweat, mostly just my forehead but you could use an extra for swampass and carry a change of boxers I guess.
if it's bright sun wear sunscreen.
try to time the intersections and lights so you never come to a complete stop and your body will stay air cooled, even at really slow speeds. when you come to a complete stop is when the sweat pours off you instantly. also, if a light is unavoidable and there's no shade at the intersection, hang back to the shadow of the nearest tree or building to stop.
