The WeatherTrek riding blanket protects the horse's back and prevents dampness while riding. The blanket is made of a sturdy, breathable, water-resistant nylon material. Has net lining and a teflon coating from DuPont. The blanket fits well and is easy to adjust around the saddle with a strong Velcro strap. The reflective trim around the contour and Z logo help make this rug visible both day and night.
