Sure you can layer your running tights over other pair for warmth. But why put yourself through that bunchy wrinkly mess (and port-a-potty nightmare) when you can wear fleece-lined running leggings? The Actra Jillian Pants ($39.99, Lady Foot Locker stores) combine the best in performance and warmth without the hassle of tugging on an extra layer, and with their reflective accents, you'll stay safe when the weather reduces visibility. Throw your phone, keys, and credit card in the zippered pocket at the back of the waist, and you're ready to go.
