This is a hand-knitted sauna hat. The color is a faded denim blue. 100% acrylic. There may be some color variations in the yarn, but this is not a stain. The face area has an openwork pattern, so you can see even while wearing it, such as the TV in the sauna room. If you soak it in cold water, wring it out, and wear it, you can enjoy the sauna while keeping your head cool. You can stay in longer than usual. For warming up, sweating, and comfort. Please wash in a washing machine using a laundry net. KOAMI original creation. A unique design. It's also cute to wear as a regular knit hat. There's also a ring on the top of the head, so you can hang it on a bag hook when you're not wearing it. I enjoy knitting and knit as I think of things. This is a handmade item by an amateur, and I would be happy if someone likes it. Thank you. #KOAMI's wear accessories #Cap #Beanie #Hat #Outdoor #Bath supplies #Stroll #Tulip hat #Beret #Handmade #Knitwear
