Tai Chi uniform – cotton/linen Deep Blue This Tai Chi uniform is made from a comfortable blend of cotton and linen. The natural-feeling fabric is pleasant on the skin and slightly thicker and stronger than our thin and supple cotton clothing. The deep blue color gives the uniform a classic and refined appearance suitable for both training and demonstrations. Features Comfortable cotton–linen blend Natural feel, soft on the skin Slightly thicker and more durable than thin cotton Deep blue color (太极藏蓝亚麻) Care InstructionsA shrinkage of 3–4% is normal; in rare cases up to 10%.
