t-shirt and shorts and tennis shoes in hot summer days, but wear a helmet 99% of the time.
IN cooler weather under 80, I do wear my mesh armored cycle jacket as well and gloves of some sort with pants of some sort of course.
I side on the area of comfort over protection. It will haunt me some day if I ever go down am sure.
with the correct mesh gear u will be cooler than riding with nothing like u said.
it will keep the direct sun off of you keeping u cooler.
