ThinLine+Plus (1/4", 6.4mm) is thicker and designed for beginning riders, horses in high impact situations, or horses with sore backs. ThinLine+Plus is endorsed by Veterinarians, even for severe back problems such as kissing spine. It is the #1 choice of Equine Chiropractors and Massage Therapists.
The top choice for many great riders. Kent Farrington rides every horse, every day in a ThinLine+Plus Contour pad, and has done so for more than a decade.
