Short sleeve shirt and short pants. This is a good time of year for riding. Yesterday it was 58 at 6:30 and got up to 82 by 4:20. The day before when were riding was about the same. I took a light jacket along and even had my half windshield mounted but didn't need the jacket and the windshield came off shortly too as I didn't need the small bit of warmth it provided and when going over real steep terrain, it impedes the view of what is just over the ridge. I wear goggles and really prefer no windshield at all. Nice to have one that snaps on and off easily.
