This is a martial arts under-belt made from fabric woven with karamushi (ramie) fibers. Length: Approximately 252 cm Width: Approximately 8-8.5 cm Adjustable Range: We can accommodate your desired size within a range of approximately 20-30 cm (e.g., 70-90 cm). Velcro: Available in black or red. If red, we will sew two pieces of soft tape together as longer ones are not available. Although it's not a stiff belt, it doesn't stretch, so you should be able to tie it securely. The fabric is sewn with eight layers. Because of this, it's difficult to sew, so we use thin thread and a thin needle. To make the belt longer, the starting part is made with four layers of fabric, making it easier to wrap. The last photo shows the quality certificate of the fabric used. About Karamushi (Ramie) From the Okuaizu Showa Village Promotion Company website: "Karamushi," also known as ramie, is a perennial plant of the nettle family, cultivated in Showa Village as a raw material for high-quality cloth. The fibers extracted from the stems of karamushi grown in the fields are used in Showa Village's karamushi weaving, as well as in the raw materials for the Important Intangible Cultural Property Echigo Jofu and Ojiya Chijimi fabrics. "Karamushi weaving" is highly breathable and absorbent. The woven fabric is light and supple, and the cool comfort provided by its unique firmness is said to make it impossible to wear other fabrics once experienced. In 2017, the long-standing techniques were recognized, and "Okuaizu Showa Karamushi Weaving" was designated as a national traditional craft.
