To hike the CDT I wore my zip-offs as shorts. When walking into the sun it was unbearable. I clipped a large bandana to my shorts pockets in front. This would shield my legs from the sun, kind of like a skirt, without adding any heat to my body.
I wore a Jolly Gear button down hoodie. I really liked the hood a lot. It provided good shade for my face. What I did was clip it to the bill of my cap with a binder clip. It added warmth when it was cool and kept mosquitoes away. It did feel a little hot in the sun but it provided shade for my face so that made up for it. The rest of the shirt is just a button down shirt. The fabric on the sleeves is very light. When it was hot out I was hot but I would have been hot no matter what I wore.
