These Soft and Stylish Long-Sleeve Layers Are Perfect For Chilly Fall Runs

This lightweight, form-fitting half-zip baselayer made by Icebreaker ($105) is made of 83 percent merino wool, providing superior warmth and breathability, with the ability to wick sweat — preventing that clammy cold sensation.

The half-zip and thumbholes provide further coverage, but if you get hot, you can always lower the zipper to let the cool breeze in. The stretchy fabric contains lycra and snugly hugs your torso, keeping your body heat in. It comes in blue or black.
