So your Fall running tights aren't quite cutting it in the cold weather. You need to kick it up a notch with slightly warmer, wind-resistant pants. I just got a pair of these Power Stretch Tights from EMS and they're my new favorite thing. I went running while visiting a friend and even though it was 20° F, these pants kept me toasty warm. The design is fitted so they hug your body and support your muscles, but they're stretchy too, so you can move freely. The interior has a thin layer of soft comfy fleece and the outer layer is smooth, so after a few washings, they still look brand new. The waistband is elastic, so it stays put, and there's a small zippered pocket in the back for money or an ID. The best part about these pants is that they're wind-resistant, so even when the wind is blowing, your legs stay protected from the cold. Another great thing? They're on sale for $55 — down from $69. If you're committed to running in the cold, these pants are a must.
