What is multifunctional headwear? One product can be worn in up to 12 different styles. Wear it as a beanie, a neck gaiter, face mask, balaclava, ponytail holder or headband. What's your favorite way to wear it? Bob's Sports Chalet carries Buff, the original multifuntional headwear company, along with many others. Make sure to review the fabric content, as many of these headwear products are made from a variety of fabrics from merino wool to ultra stretch fabric with UPF protection.
