Raptor is the official eyewear choice of HEAD pros for many reasons. For starters, it features a modern and lightweight impact-resistant frame as well as fitted temples with a rubber inlay for a comfortable and stable fit. The extra durable anti-scratch and anti-fog treated lenses are interchangeable and come in three distortion-free polycarbonate versions so that your eyes can perfectly adjust to court conditions: clear lenses for all courts, amber lenses for glass courts or darker playing conditions and smoke lenses for outdoor or extremely bright conditions. The Raptor also provides 99. 9% UV Protection as well as a non-slip nosepiece to help keep you focused. And don't worry about these slipping: an adjustable elastic strap holds the eyewear in place at all times. A high-quality lens cleaning bag sweetens the deal just a little more.
