Quality handmade in the USA. Versatile chemo cap – can be worn indoors and outside, doubles as a great sleep cap or yoga hat. I love this cap because it is SO comfortable! Size: My hats will fit heads that measure 21 – 22 1/2 inches. If your head is larger or smaller than these measurements, I’ll be glad to custom size your hat at no extra charge. Just be sure to include your measurements with your order. (Measure all the way around head at forehead level). Fabric: 95% Cotton and 5% Lycra. Washer/dryer safe (wash in cold water, dry on low heat to avoid shrinking).
