I usually struggle to get hats and headbands to fit as it seems my head is above average size, so I can never wear "one size" things. I was very pleased to spot the extra stretch version of your headbands, they are just right for me. I actually use the bands as a hat/ sleep hat, as I have total hair loss and it gets a bit cold in the winter. They are perfect for using as a sleep cap, just to keep my head from getting too cold and unlike other hats don't hold on to any dampness. I like these type of multi use headbands, They are just the job and easily stretch to fit my 23 inch head, perfect to carry in a pocket and use as an emergency mask too. I am glad I now have a selection of patterns, so i can change frequently, and they are so easy to wash and are dry in no time at all. I might treat myself to more. Highly recommended.
