ALTALIST KAKU SP2 Sports Sunglasses

KAKU SP2 is a hidden full-frame photochromic sports eyewear featuring VIV20 coated lenses (some lenses are clear photochromic). It combines the lightweight feel of rimless glasses with the protection of a full-frame design. The widened lenses offer a broader field of vision, while UV protection and VIV20 high-contrast technology enhance environmental awareness and improve road visibility.

1. Photochromic lenses darken quickly under sunlight or UV exposure to block strong light and absorb UV rays; they return to a clear, transparent state in low-light conditions.

2. Hardened coating and widened lens design provide enhanced protection.

3. VIV20 lenses improve color recognition, sharpen vision, and enhance the ability to detect motion and changes in surroundings.

4. The frame and temples are made of ultra-light, highly flexible materials that resist impact and abrasion, reducing the risk of breakage and minimizing facial friction during sports.

5. Soft rubber-covered nose pads are interchangeable in two thicknesses (S/L) to suit different face shapes.

6. Flexible temple tips can be bent for optimal fit.

7. Shark gill-style vents on both sides of the frame improve airflow and reduce fogging.

8. Accessories: glasses case, storage pouch, cleaning cloth, prescription lens insert, S/L nose pads (M size pre-installed), user manual.
