Details
Specialized's SL Jacket could be the difference between going long and going home. It's made of light, protective polyester for excellent water resistance and packability, so it easily fits in a jersey pocket. For maximum venting this fine top has strategically placed mesh panels, while the close-fitting waist provides a secure fit and keeps road spray away from your kit. And, there are reflective accents for safety.
Also available in Ion (image unavailable from manufacturer).
