A long time ago, I was covering the Iditarod Trail Sled Dog Race in Alaska, Cabela's, as the main sponsor of the event, gave away the sweetest Polartec fleece caps to the journalists covering that race. To this day, that hat is my go-to hat for cold weather running and cross country skiing. It's not too heavy that is smothers you, but warm enough for aerobic adventures when the temperatures dip into the 20s. Click here to go to the store and order your hat. I'll take orders and then have a quantity made to ship. After that the price goes up on any that are ordered above and beyond the initial order placement. Details on the hats are on the link above.
