This multipurpose garment can be used for ever so many things ... cap, hairband, scarf, balaclava, do-rag, and you can probably think of more. It comes with instructions. We use ours around our necks to keep cold air out in cooler weather, to keep cool in summer when we wet them, and to protect against chafing from the leather gear. Additionally, the UV Sun colors offer UPF50 sun protection.
