Our exceptional chemo beanies for hair loss provide the perfect fit for men and women. This is due to their ability to extend to 57cm. In fact, our hats adjust to the size of the head. This is thanks to the elastane inside them. So, they stretch. As a result, our Chemo Beanie will fit most average sized heads. As with all our headwear, our Chemo Beanies provide a snug and comfortable fit. So, no matter whether you are seeking headwear for exercise, to look good, or to keep you cozy in the winter. Our unisex Masumi Chemo Beanies are right for you!
