The Windstopper Base Layer Thermo Long-Sleeve Shirt from Gore Wear is such a quintessential part of our cycling wardrobe that we can't imagine not having it in the arsenal. Ideal for a multitude of other sports as well in ever-changing weather conditions, having a thin, elastic wind blocking membrane on the front, sleeves, shoulders, and kidneys protect vital body parts and allows you to stay much warmer without the bulk. Its extra-long back offers additional protection and it uses a minimal amount of flat-lock seams to keep friction, irritation, and chafing a thing of the past. Add in its Thermo-stretch insulation and water resistance and you have a go-to base layer for winter rides.
