This is an "ane-san cap" made with sashiko stitching on bleached cotton. It's reversible, with a plain white back. The bleached cotton feels comfortable, and the cap has a soft, airy fit like an "ane-san kaburi" (a traditional head covering), allowing for ventilation and sweat absorption. It's easy to put on and take off, without the need to tie it like a hand towel. It's convenient for outdoor activities such as farming, gardening, and fieldwork, as well as for indoor tasks like cooking and serving food. This is a handmade work cap.
