The SP-3750 Photochromic sunglasses are the best choice for mountain biking that strike a delicate balance between protection, performance, and looks. Yes, it’s true that while function is critical, styling can never be discounted when it comes to something you wear on your face.

Best Fit - The TR90 frame is designed with Mirror Adjustable Range Design that provide a best fit on your face due to easily adjustable nose pieces and temple arms that can be manipulated to provide you a truly customized and secure fit. The straight temple arms off you the best helmet compatibility. 

Photochromic lenses. Engineered to actually vary tint depending on available light, which in turn makes it easier to deal with rides with variable light conditions. This can be tricky, especially if you ride in a place where the trails poke in and out of the forest, meaning you need a lens that works in the darker situations, though it may not feel dark enough when you’re out in the open. 

Coverage - It’s never fun to get something in your eye, especially when you’re bombing down a rocky section of singletrack. SP-3750 sunglasses provide ample eye coverage, including on the periphery. The wide lenses cover and protect your entire field of vision, and protecting your eyes from trail obstacles.

Clear vision - the High Definition (HD) clear lenses, filter out two distinct wavelengths that cause color confusion, giving you the clearest and richest pictures of your favorite natural landscapes.
