The R.J. Classics Ladies’ Sienna 37.5® Training Shirt has that timeless, yet sporty styling that will always look appropriate wherever you ride. Its patented thermoregulation technology has proven to help your body manage its core temperature and therefore, increase stamina. It keeps you comfortable by helping your body to maintain an optimum core temperature of 37.5° Celsius (99.5° Fahrenheit), which is ideal for peak athletic performance. The particles are naturally derived and work for the life of the shirt, meaning they will never wash out.
Additionally, the main body fabric is rated UPF 50, making it a great shield against the sun. Tonal mesh panels under the arms add cooling ventilation.
