The multifunction bandana started in Spain and is a seamless headscarf. Because the headscarf can be used in different ways or even worn, it is famous for its ever-changing headscarf! The ever-changing headscarf is used outdoors, and it plays a role in sun protection and sweat absorption in outdoor sports. The functions of dustproofing and decoration are deeply loved by outdoor sports enthusiasts. After being introduced into China in 2000, the ever-changing headscarf has been highly sought after by domestic outdoor enthusiasts. Its shape is similar to that of a sleeve without rubber bands. It has excellent elasticity and texture, so it can change a variety of patterns without causing pressure on the skin.
