- Monks are said to lose their abilities when "wearing armor" (PHB p. 39) -- that is, any armor.
Actually, do note however, that the monk's Evasion ability speciffically notes that they can use it when in Light or No Armor.
So a monk -can- evade with a shield, or chain shirt on, or whatever. But their other monk stuff would still be reduced/subject to ASF as normal if they did so.
