This Christmas I came home for the first time in over 3 years and was handed the rude awakening of an 7º day. I was on my #rwrunstreak so skipping my daily run was out of the question. I hadn't given my Oiselle apparel the test of an icy run yet either, so that was exciting.
What I wore for 7º, with a slight wind:
The new Lesley Tights under Lux Pant. I have to say, even in 7º this was a little over kill. The Lesley Tights + high ankle socks (or even compression) would have been more comfortable. I'd save the double pants for under 0º.
Next, my base layer was Flyte Long Sleeve. Perfect with the thumbholes, so no skin was exposed. Then I added the Big O hoodie, which has become a favorite running top this holiday. It's fleecy but not stifling. In fact I feel like it's pretty darn perfect as a top layer for an easy cold weather run.
I should add that I wore mittens and a hat. I also carried my iPhone in a mitten to keep it from shutting down in the cold.
Bonus layer: I would throw the Flyer Jacket over top the hoodie or double base layers if the 7º had been accompanied by wind or snow. The Flyer Jacket is surprisingly warm, in fact unless it's under 38º I'm just too hot in this jacket. Which is all part of its magic... seriously don't underestimate this guy.
Dressing for the cold can be tricky and you can easily end up being WAY TOO HOT. So remember you shouldn't be warm until a mile in. If you are... you're going to be too hot. And layers are king.
