All Martin Saddlery flank cinches have biothane keepers for longevity. The contoured ends will not interfere with spurring. They are made of heavy saddle skirting with a latigo liner, sewn together with heavy nylon thread. Then they are hand rubbed, edges are dyed, and borders are stamped. Roller buckles are secured with copper rivets. Sizes available are 2-1/2" wide 35" long, 4-1/2" wide 35" long, 8-1/2" wide 31" long. Available in natural skirting leather only. Don't forget to add a flank cinch hobble strap to your order.
