Running outside in New England brings many challenges, staying warm is one of the biggest. I have tried several different types of base-layers, but always seem to be cold half-way through my 5K. The Smartwool, NTS Light 195 Zip T, has been the only base-layer that keeps we warm through my whole run. I highly recommend this product, and I will be buying more Smartwool products in the future. Keep running!
