I wear a mesh jacket when it is hot wih a under armor long sleeve tee underneath, dampened when hot. Mesh pants on long trips with shorts underneath. Always gloves. Always with the armor. Also to remember, my Doctor states is to protect the skin from the sun and wind. As I age the years of little protection from the elements, Viet Nam, 21 years Navy and mc and other outdoor activies since the 1950 s, are catching up. Skin cancers are starting to appear in my mc club as we pass 60. I had deep one taken off my right forearm in Dec. No brake lever kept me on the road with lessened grip while healing. I still cheat occasionally like when I am riding by the beach in Panama City, but in my heart I know that people are looking at my Spyder not an old man trying to appear cool.
Stay cool.
