I’ve worn a Joe Rocket mesh that I still have in the heat. The airflow is significantly noticeable when moving, if I stopped for a break it came off immediately. On the trike I feel a bit safer I will say. I know I can get hit but not as worried about falling or sliding in a curve anymore.
I wear long sleeve "fishing" shirts over a T-shirt. (Columbia, etc) Or arm sleeves with T-shirt. I also have "fishing" gloves that I wear when riding long distance in sun. All have SPF 40-50 protection.
I find it funny they have started adding SPF protection to shirts. Kinda no bleep.
I wear fishing shirts in the woods. There are tons of light shirts out there now.
But a riding shirt that is not a jacket, is not going to happen. You can wear a mesh jacket as said, got one, don't wear it much because around here hard to find a day with warm mornings and nights so carry leather too. A shirt is a shirt is a shirt. Long sleeve t-shirts, or denim work if you just want sun off you.
Mesh Dainese jacket with armor pads, not corny/ racer- looking
Too expensive, from my Ducati days.
Once rolling very cool and has some protection.
L/S T-shirt under.
Has held up well, it's black w hidden reflective.
Color doesn't seem to be a factor w mesh.
If I were buying now would choose visibility.
