How big our your babies? Ours weighs about seven pounds, and she is fine to go out for a minute or two to potty, without a coat. She loves snow. If she is out very long, she does have a coat. But she seems to do much better when it is cold than when she gets hot. We don't leave her out any longer than we can stand it ourselves, without a coat.
Unless you will be out for long periods of time, or unless they are very tiny, they will be just fine.
