Vaqueros' ropes, also known as RIATAS, are an essential tool for cowboys and horsemen. They are made of braided rawhide or leather and are used to lasso and control livestock. RIATAS are typically around 30 feet long and have a loop at one end for the hand and a knot at the other end for the lasso. They are an important part of the traditional cowboy lifestyle and are still used today by ranchers and horsemen.
