These simple hakama are made from tetron, a polyester and rayon (artificial silk) blend. Strong and durable these are great for practitioners seeking a practical and economic pair of hakama to get down to some training. They are suitable for kendo, iaido, naginata or kyudo - however due to the hera (plastic hook for the obi) and stiff koshi-ita (backboard) we do not recommend these for Aikido as ukemi will be painful.
