About: Our best-selling Brighton Base Layer features an engineered Merino mesh that’s more open around your core, with a closed knit on the sleeves for more warmth in your extremities. We designed it specifically as a training base layer to be worn under a mid-layer or a jacket, but its seamless construction gives it a comfortable, flattering fit that’s not too tight to wear all by itself. Because the Brighton Base Layer is intended to be worn against your skin, we wanted to eliminate any points of possible irritation or chafing. So we went to Europe and partnered with one of the most innovative seamless factories in the world. Show your Windy City spirit in this specially screen-printed Brighton Base Layer, a seamless merino top perfect for mileage in cold weather. Merino Wool wicks moisture and provides a high level of odor management. Seamless construction eliminates seams to avoid chafing or rubbing while running. Features: •52% Wool, 28% Nylon, 20% Polyester, 16.5 Micron, 145 gsm
