This is a kendo tare (waist protector). It is hand-stitched with 1-minute stitching. It is likely a general men's size. For reference, it fits me perfectly, and I am 175cm tall and weigh 75kg. Machine-stitched armor seems to be popular these days, but this is a perfect item for those who want the high-quality feel that only hand-stitching can provide. If you are interested, please don't delay. Currently, it is on sale for 6,000 yen off until the 31st. Take this opportunity.
