The Party Rests in Armor

I received a heavy set of steel chainmail for Christmas. I wear it around town, under my huge sweatshirt, three sizes too big. It's about thirty pounds of extra weight so maybe I will burn off some of the Holiday Cheer. In any case, I slept in my armor last night to no ill effect. So I suggest that if you require your Player Characters to sleep outside of their armor when they rest, perhaps you should make an exception for chainmail. It is not uncomfortable, and I'm a light sleeper.
