While looking at the UV damage done to the gelcoat on my glider, it reminds me how much UV radiation we are exposed to while soaring. Particularly out west!

Coolibar (no affilation) is in the Sun Protection Clothing business. Take a look at their website. They are making some great products with innovative materials.

I particularly like their Andros Shirt and fingerless long gloves.
Both with UPF50+ protection.

I got a definitive answer by an aviation plexiglass manufacturer. I don't know how to post a picture here of the UV graph of two different colors with and without extra UV protection. It looks like they all block UVB. It is UVA where they differ, from blocking only under 377nm, to blocking up to 400nm. So you won't get sunburned under any canopy, but you will get various amount of deeper skin damage from UVA based on your particular canopy.
