On the plate, of course I don't have to worry about bundling up as much. On the bases, it is usually a t-shirt, then a long sleeve cotton tutleneck in the appropriate color, and my long compression underpants with (hopefully my partner has them!) Honigs Polywool slacks, which seem to keep me a bit warmer than their regular slacks.

Maybe being from Oregon, I am a bit more acclimated to cold, damp conditions for baseball!

Oh, gloves! Can't forget gloves!!! I have some black neoprene fishing gloves for those really harsh days!
