RT100 Kato frameless cycling sunglasses for men Q588k Gold, wrap-around lightweight with brown gold multilayer lenses

RT100 Kato frameless cycling sunglasses are lightweight, wrap-around sports shades with cylindrical PC lenses, TR90 memory arms, and full-gold multilayer coating for UV400 protection and enhanced contrast.

Built for cyclists and active commuters who want a minimal, aerodynamic profile without sacrificing protection, these sunglasses combine a rimless look with durable materials and optics tuned to outdoor riding. The design reduces visual obstruction when you’re in a forward-leaning position while providing impact-resistant lenses and adjustable fit features for long rides.

How do these sunglasses improve vision and contrast on the road?

The RT100 Kato uses a brown base lens with a full gold multilayer Cat.3 coating to reduce blue light and reflect glare. This combination enhances contrast, improves depth perception, and makes red, yellow, and brown tones more distinguishable in mixed lighting.

• Brown lens base reduces blue light by up to 30% for warmer, clearer sight.
• Full gold multilayer coating reflects glare and infrared rays to reduce eye fatigue.
• Uniform luminance transmittance minimizes side-view distortion and visual artifacts.

Are these frames comfortable and stable during vigorous rides?

Yes — RT100 Kato frames use TR90 memory thermoplastic for flexible, lightweight arms that resist deformation. Adjustable nose pads and temple supports hold the glasses securely through head movement and helmet use, while the wrap-around shape keeps wind and debris away from your eyes.

• TR90 memory arms for durability and flexible fit across many face shapes.
• Adjustable nose pads to customize pressure and prevent slipping.
• Rimless wrap-around silhouette reduces interference when leaning forward.

What level of protection do the lenses offer?

The lenses are made from impact-resistant polycarbonate (PC) and provide 100% UV400 protection against UVA and UVB rays. They are non-polarized, which helps maintain natural depth cues while still guarding against harmful sunlight and small airborne particles encountered on the road.

• Quality PC lenses for enhanced impact resistance.
• 100% UV400 blocking of UVA and UVB radiation.
• Non-polarized optics preserve reflected-surface details for riding safety.

What comes in the box and how should I care for these sunglasses?

The RT100 Kato arrives as a complete kit so you can protect and maintain the glasses between rides. Proper cleaning and storage extend lens life and preserve the gold multilayer finish.

• Includes protective hard case, drawstring pouch, and microfiber cleaning cloth.
• Store in the hard case when not in use to prevent scratches.
• Clean lenses with the provided microfiber cloth and mild solution; avoid abrasive cloths or solvents.

Who is this for: Cyclists, road riders, and outdoor athletes who want a lightweight, aerodynamic, and stylish sunglass that balances high-contrast optics with impact protection. These are suitable for daytime road cycling, commuting, running, and driving when you need a secure fit, reduced glare, and a frameless profile that won’t block your field of view.
