I really want to get these boys outside more this winter but I've always worried that they will be too cold. In the past I've always bought the Lands End Squall Coats - wind/water resistant outer with thick fleece lining. Now I am wondering if it might be better to go with a down coat, but then I worry that they might overheat. For moms in colder climes, which do you prefer and why? I'm in Ohio so it is not too cold, but it can get down there a bit.
