100% cotton Snug fit Made of double-layered cotton knit in a tube shape. The top is not sewn together but twisted, so it can be worn like a knit cap. The tighter you pull the bottom, the tighter the top becomes. Depending on how you use it, it can be a hat, turban, or neck warmer. Since it's cotton, it won't irritate your neck when worn. If the shape gets distorted, wear it with the side seam at the bottom and pull the bottom tightly to adjust the twist, and it will become a hat. It's best to hide the seam as much as possible. Use it for walks, cooking, after bathing, or as a care cap! Custom orders are also accepted.
