Running in the winter is all about layering, and the first piece you need is a good baselayer. Enter the Saucony Boulder Baselayer. This top is made from recycled polyester blend and a French terry back to help wick moisture away from your core. The forward shoulder seams offer comfortable layering. Plus, there are dual watch windows on both sleeves (left hander’s rejoice!), so you can easily get to your Garmin watch. Be ready for the winter weather in the Saucony Boulder Baselayer.
