By knitting hemp yarns and organic cotton yarns, two different natural fibers, together, ROTOTO have created a fabric that combines the good feel of organic cotton against the skin with the breathability and coolness that are the characteristics of hemp. The sole is knitted in pile, with the image of organic cotton absorbing perspiration and hemp dispersing it. The reinforcing yarn (stretch yarn as the core yarn covered with synthetic fibers) knitted together to provide strength and elasticity is made of polyester. The characteristics of dyeing, such as "polyester cannot be dyed with dyes that can dye natural fibers," are utilized to intentionally create a wooden pattern, giving the garment a handmade, dyed look.
