Key Specifications & Architecture

Frame Material: Made from TR-90, an incredibly flexible, lightweight, and impact-resistant Swiss polymer.
Weight: Only 27g to 28g (depending on the lens), which makes it almost unnoticeable on long endurance rides.
Fit Customization: Features an adjustable rubberized nose bridge and anti-slip rubber temple tips with a pressure-reducing structure to prevent slipping when you sweat.
Ventilation: Strategically cut air vents on the outer top edges of the lenses and temples maximize airflow, reducing the risk of fogging during hard efforts or humid descents.
Prescription Friendly: Every set comes with a detachable, clip-in optical inner frame (supporting up to -4.00 diopters of myopia and -2.00 of astigmatism).

Two Lens Variants Available

The KAKU SP1 is usually sold under two distinct lens configurations depending on your environment:

Feature	Polarized Version	Photochromic Version
Lens Material	TAC (Triacetate Cellulose)	Polycarbonate (PC)
Best Used For	Intense, direct sunlight (Beaches, open highways, bright snow)	Changing conditions (Dawn/dusk, forested trails, variable overcast)
How it Works	Fixed Category 3 tint. Filters horizontal light waves to instantly eliminate blinding glare from roads, car hoods, or water.	Transitions dynamically based on UV exposure. Automatically darkens in bright light and clears up in low light (Cat. 1–3 or 0–2 depending on tint color).
Protective Coatings	Hard anti-scratch coating	Hard anti-scratch + UV400 shield
