Wool does hold water. The old polypropylene synthetic fabric (like Lifa long underwear) will hold almost no water so could be better for heavy sweaters exercising heavily. Don't think I've ever seen a bra of polypro, though. It's pretty stretchy stuff.

Wool isn't necessarily going to be able to keep you warm, but it is a better insulator when wet than other fabrics so you might not get as cold as quickly. If you're getting cold when your wool bra gets wet, I recommend adding a wool undershirt too. I've loved that combo under my cycling jersey in cold weather. Remember too that there are different grades of wool - thick vs thin - so that will probably affect its properties.

that sounds actually painful to me.
