Shimano Unisex Sunglasses S-PHYRE SL GR Green Sapphire

The Shimano S-PHYRE SL is the super-light performance cycling sunglasses for riders who prefer a sleek, rimless design and clear vision. The single-piece lens is ultrasonically welded to the nosepiece, providing a wide, distortion-free field of view — ideal when reaction time and situational awareness matter. Shortened, form-fitting temples make it easier to put on and take off under a helmet and ensure a secure fit even on rough terrain. This variant comes in the frame color Green Sapphire and with the RIDESCAPE GR lens, which is specifically tuned for gravel conditions. Shimano states the weight of the S‑PHYRE SL at around 23.7 g, making it one of the lightest cycling sunglasses in its class.

• Single-piece lens with ultrasonically welded construction for clear, wide vision without distortion.
• RIDESCAPE GR lens with approx. VLT 22% to enhance contrast on gravel, natural tracks and asphalt.
• Super-light construction (approx. 23.7 g) for minimal fatigue on long rides.
• Shortened, form-fitting temples for secure fit and effortless wear under a cycling helmet.
• Reversible nose pad for individual adjustment to different nose shapes.
• Frame made from bio-based Rilsan Clear G850 Rnew and double-injected, non-toxic TPE temple tips.
• UV400, scratch-resistant multi-layer coating and oleophobic/hydrophobic properties according to Shimano lens technology.
• Subtle ventilation opening at the top edge of the lens to reduce fogging in changing conditions.

Technical Details and Features

The rimless concept of the S‑PHYRE SL minimizes air turbulence and supports clean aerodynamics, while the ultrasonically welded connection between lens and nosepiece increases the field of view and reduces optical distractions. The RIDESCAPE GR lens was tuned for gravel use: it emphasizes subtle transitions between gravel, dirt and asphalt, which provides added confidence on fast descents or in light-changing sections. With a visible light transmission of around 22% (Cat. 2) it covers typical Swiss gravel weather from bright to slightly overcast without unnecessarily tiring the eyes. The lens is based on a lightweight Polyamide (PA) substrate, which Shimano uses for its high clarity and durability; it also features UV400, scratch-resistant and oleophobic/hydrophobic coatings for consistently clear vision. The frame is made from bio-based Rilsan Clear G850 Rnew, the temples end in grippy TPE, and the reversible nose pad makes fine-tuning the fit easier.

Use Cases and Benefits

With the RIDESCAPE GR lens the S‑PHYRE SL shows its strengths exactly where Swiss gravel routes vary: from Jura gravel to forest tracks and paved connecting sections. The contrast enhancement helps detect edges, potholes or loose stones earlier and to execute line changes cleanly. Thanks to the super-light construction and shortened temples, the glasses remain comfortable and non-slip under the helmet on long brevets or quick after-work rides. The subtle ventilation opening supports clear vision during temperature changes, for example after climbs or in damp conditions. Those who prefer a more compact, unisex fit — including reversible nose pads for fine adjustment — will find a versatile option for Gravel, Allroad and Road here.

Fit and Comfort

The S‑PHYRE SL was designed to sit naturally even on narrower face shapes without creating pressure points. The form-fitting, shortened temples are compatible with a wide range of modern cycling helmets and make quick removal easier in everyday use. The reversible nose pad offers two contact surfaces of different thicknesses, allowing you to fine-tune the glasses to your facial geometry. Together with the lightweight PA lens and the grippy TPE ends this delivers a stable wearing feel that does not slip even on rough gravel sections. The combination of rimless optics and a wide field of view lets obstacles appear earlier, making line selection more intuitive.

Materials and Technology

Shimano uses Rilsan Clear G850 Rnew, a bio-based polyamide, in the S‑PHYRE SL to reduce the use of fossil raw materials — without compromising stiffness and durability. The Polyamide lens of the RIDESCAPE series scores with a low refractive index and a high Abbe value, which benefits optical clarity and color purity. UV400 fully protects the eyes from UVA/UVB, while scratch-resistant and oleophobic/hydrophobic coatings repel water, dirt and fingerprints. For gravel use the GR tint with approx. 22% VLT is tuned to emphasize surface structures and make transitions more visible. This combination of technologies makes the S‑PHYRE SL a lightweight, robust and everyday-ready sunglasses for cycling in Switzerland.
