Sprint FX Sunglasses (with interchangeable lens)
Zone3 Ultra Speed Sunglasses are designed for training, racing and everyday use. They offer fantastic comfort, vision and style, but at an affordable price.
Below are the key points of the design:
1. Made from an innovative TR90 composite material designed in Switzerland. This thermoplastic technology is incredibly strong, flexible and lightweight. The flexible nature ensures that the frames can bend under pressure and contour the face to maximize comfort. The flexible nature of the TR90 also helps improve durability if dropped during a nutritional break or damaged during transition.
2. Another key point of this TR90 technology is the extremely lightweight material that ensures a comfortable fit on the ears.
3. Polarized LMS (Light Management System) lenses are used and coated with multiple layers of titanium and silicone oxides to eliminate 100% of harmful UV rays, improve color focus and provide clearer vision.
4. Interchangeable lenses based on lighting conditions. Also included is a set of non-polarized lenses for cloudy or darker sky conditions.
5. Both lenses feature custom vents designed to work with the Anti-Fog coating and ensure the sunglasses stay fog-free. This is essential for any triathlete as sunglasses fogging up early in the cycle can be very common as water from the swim evaporates from the skin.
6. Adjustable nose pad to perfect the fit and 100% guarantee no bouncing during races. Try them on, jump up and down, shake your head, and you'll find that they're still perfectly locked in place.
7. Wrap-around style to ensure an optimal fit, especially for small to medium sized faces.
8. Each pair comes in an elegant white box with microfiber bag for storage.
