YM Agency Co., Ltd’s silk braid hats are handmade through exceptional craftsmanship using 100% 200 denier raw silk thread. They are produced at Tomioka Silk Mill, a UNESCO World Heritage site famous for its innovation in silk production. Silk blocks over 95% of UV rays and protects your scalp and hair from the heat in summer, and keeps you warm in winter. In addition to the natural white color, the hats are also available in black, navy, beige and light purple.
