These are DEFINITELY tights, they don't double as pants. They'll need something over them, for sure. The warm fuzzy interior reminds me a bit of the inside of soft, fuzzy sweats.
Problem:  The legs are quite short, and because they're footed, the crotch rides REALLY low. I think the manufacturer was using a pattern that works fine with stretchy stockings, but the polar fleece does Not stretch as much. Not a deal breaker. If I wear a pair of regular tights (pants) over top, they pull the crotch into closer to a normal location. Next time I'll buy the non-footed version, for sure.
