ALTALIST KAKU SP1 GO BIG Sports Sunglasses | Concealed Full Frame Lightweight Protection

The KAKU SP1 features a concealed full-frame design, combining the cool aesthetic of frameless eyewear with full-frame protection. Equipped with quick-reacting photochromic lenses and UV400 protection, the larger lens design provides enhanced shielding against wind and dust while offering a wide field of vision.

Advanced All-Weather Vision & Technology

• Photochromic Technology: Darkens rapidly in bright sunlight or UV rays to block glare and absorb ultraviolet light, returning quickly to a transparent tint in darker environments.
• Wide Anti-Scratch Lens: Enlarged lens with a hard anti-scratch coating delivers a broader field of view and extra protection.
• Ultra-Lightweight Frame & Temples: Made from high-strength TR-90 material with exceptional impact resistance and low friction coefficient to prevent frame breakage during impact.
• Ergonomic Comfort Fit: Features soft rubber-covered temples and adjustable nose pads for custom face fitting, alongside a pressure-reducing temple structure for extended wear.
• Anti-Fog Ventilation: Air vents integrated into both the temples and lenses improve airflow, reducing fogging and moisture buildup.
• Detachable Optical Inner Frame: Includes an optical clip compatible with prescription lenses (supports up to -4.00 D myopia and -2.00 D astigmatism).
