These Tifosi Wisp EC Fototec(TM) photochromic sunglasses automatically adjust tint in changing light, accommodating dim, sunny and hazy conditions for protection and superior clarity. EC (Extreme Contrast) Fototec photochromic lenses automatically adjust tint according to light conditions; lenses darken in bright light and lighten when there's less light. EC Fototec lenses filter blue light for enhanced reading of trail contours. NXT Trivex optical polymer lenses provide superior clarity and are virtually indestructible. Grilamid(R) TR90 lightweight nylon frames offer a consistent fit and flexibility in all temperatures and are extremely impact resistant. Hydrophilic rubber nosepiece and temple ends become tackier when wet for reliable grip during exercise and hot weather. Temple ends adjust for personalized fit and comfort. Best fits extra small to small faces. Tifosi Wisp EC Fototec sunglasses include a semirigid zippered storage case and cleaning cloth. - REI
