These are "Senpu" hakama made of 100% polyester, said to have the texture of cotton. The size is 25.5. They have been used about 10 times and were washed in the washing machine after each practice. Personally, I don't think there is any sweat odor, but please refrain from purchasing if you are concerned. There is an embroidered name on the right side near the hip. Please purchase only if you have read the seller's profile and understand that these are used kendo items. There is some wear and tear. Please refrain from purchasing if you are looking for a perfect item.
