Time to bring on the layers The Specialized Shasta Headband is designed to minimize your exposure to the elements while managing moisture buildup. Moisture wicking is provided by the Vapor Rize Knit fabrics the band is constructed from, which is also lightweight & breathable. As well as keeping you warm the Deflect UV 50+ means that you are also protected from harmful, ultraviolet rays. In low-light conditions the reflective elements will increase your visibility to motorists & other riders. Description by Rebecca, Rutland Cycling e Commerce Team
