I already use "mass quantities" of sunscreen for sun protection.

What do you all recommend, clothing-wise?

Sometimes I like to just throw on clothes and ride. I don't want dink around with slathering on a couple ounces of sunscreen. I still want to keep the sun exposure down, without having to be on a trainer inside!

I was thinking of a lightweight, long sleeved, moisture wicking t-shirt, but don't know the SPFs of shirts like that. I would think as the shirts became wet from sweat, any sun protection they give would go down and maybe I'd have to wear a couple of shirts.

Does anyone have any suggestions?
