The R.J. Classics Girls’ Sienna Jr. 37.5® Training Shirt is the perfect schooling style for even the youngest riders. Patented thermoregulation technology has proven to help the body manage its core temperature and therefore, increase stamina. It keeps the rider comfortable by helping the body 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; it will never wash out.
This training shirt also provides UPF 50 sun protection and enhanced breathability with mesh underarm panels. Some colorways feature a unique patterned mesh, while others feature a tonal mesh.
Imported.
Machine wash inside out and separately, cold, gentle cycle. Do not use bleach or fabric softener. Dry flat. Do not dry clean.
44% polyester/44% 37.5® polyester/12% spandex.
