If temperatures rise, the delicate balance between overheating and maximum exertion becomes a high wire act. Fox Racing's Aircool Full Zip Short Sleeve Jersey combines its desert climate prowess, cross country fit expertise, and Aircool fabric so you have the upper hand when the sun's at its highest. To keep your internal thermostat in the safety zone, Fox's Aircool polyester knit features channels that encourage airflow and help direct moisture from your skin. For even more ventilation, this jersey's contoured Aircool panels are joined with mesh vents for maximum cooling. Along with comfort and functionality, the Aircool jersey's cut and elongated rear hem conform to the body while riding. Additionally, Fox included three rear pockets for holding all of your nutrition, tools, and accessories. There's even a fourth zippered pocket with an audio cord interface.
