1. Dressing Properly
Lululemon Vinyasa Scarf: good for keeping your neck, ears, and chin warm without being heavy (buy here)
Lole Quarter Zip: This lightweight sweatshirt is perfect for running because it is warm but breathable, and super cute! (buy here)
Eddie Bauer vest: My favorite versatile accessory, I wear this on a daily basis as well as when I run. Its super super light but the warmest vest I have ever own!
Saucony Leggings: Warm and simple, these leggings are awesome. (buy here)
Gloves: Any light gloves with a smartphone compatible touch are super important, that way you can keep your hands warm and not dry and cracked while still being able to change the song on your phone.
Also, you might want to wear a hat as well or something to cover your ears so that you are very comfortable
