These Seasalt Handybands are made from organic cotton and they really are so handy. You can wear them as a neckwarmer, a hairband and also to cover your hair in the Summer. Wear it to keep your ears warm when you are out walking and it's windy. I personallly wear one under my baseball cap after I've been swimming and my hair is wet, I never dry my hair at the pool and I have never gotten a chill, even in the Winter. I put it down to my marvelous handyband, which I have one or two of as they are just so handy!
