When it comes to riding in cool and damp conditions, it's hard to beat the thermal regulation properties of natural Merino wool. The same is true when it comes to the Pearl Izumi Women's Pro Merino Thermal Jersey. The 60/40 blend of wool and nylon won't stretch out of shape and is more durable than wool alone. The hand-stitched details also add an understated touch of class. The rear of the jersey has three pockets plus a zppered pocket that will carry whatever you need for your ride. Lastly reflective elements are found throughout the jersey to keep you visible in low light conditions. The Pearl Izumi Women's Pro Merino Thermal Jersey is offered in multiple sizes and two colors. Please refer to the size chart to help determine the best fit for you.
