I have a Saucony ViziPro Sportop long sleeve mesh shirt that I wear when running at night. It's super light, not water or windproof, but I wear it as a top layer. I just looked online & found a place selling them for $23. I bought mine for full retail price. Works great & is very versatile, as I can wear whatever I want underneath (I would buy it one size bigger than normal, to allow for other layers underneath)
