+1 on most anything Nordic XC skiing gear being good for biking. Requirements are closely related (long arms, long back for hunched over position, wind proof front). Also, good XC skiing gloves have padding/heavier material in exactly the right spots for brakes and shifters.

A lot will depend on what kind of "winter" OP is referring to. Cold and snow means you can steer clear of waterproof garbage bag stuff except for the transition period, warmer and rain is obviously different.
