As you may or may not know, I have developed a love for running. Even winter running! At first i was a little intimidated by the thought of running through snow in freezing temperatures and crazy wind speeds. But now that I know how to dress, it's really fun! I still don't love the wind, but hey, it's just an added challenge if you are running against it, and helps you along if you are running with it!
It's important to wear a snug fitting base layer that wicks moisture away from your body. If your skin is drenched in sweat, you will feel colder. I wear a moisture wicking yoga top.
I don't like to wear bulky sweaters, so I add two more thin layers: a thermal waffle shirt, and a t-shirt over top.
Running jacket (I like the ventilation, even when it's cold), hat and scarf. This particular night, I didn't wear the scarf for too long. I ended up tying it around my waist after 10 minutes. Very stylish, I know. I also wear north face gloves. I don't think these are specifically for running, but they are great. I've seen a lot of other people wearing them too.
My legs stay nice and warm.
