This is a sweat-absorbent garment to wear under a mugwort steaming cloak. When using a mugwort steam, wearing this under the cloak makes a huge difference in how unpleasant the sweat feels. Also great after a bath in the summer. 100% cotton. Features small, affordable buttons on both sides. Free size, comfortable fit. Light blue color. Used about 10 times. No fraying, but it has been used by someone else. Please understand this before purchasing.
