The Do is made with a double-layer of extra heavy duty sashiko cotton fabric with hishizashi stitching for the bottom half. Made to be even thicker and sturdier than the Ki Model, whilst keeping the gi soft and comfortable to wear. The Sashiko fabric is woven in Japan and possesses an impeccable appearance and texture. Because it is double-layered, it is thick and warm, great for practice during the colder months of the year or for practitioners that perform a lot of ukemi. We naturally include all of our Aikido specific tailoring like deeper arm pit cuts and a seamless back - this means you can get the most out of your movements and ukemi with confidence.
