Rev Sky Black S

React Rev Sky Black S

The React Rev Sky Black S is a photochromic sports sunglasses for demanding cycling in Switzerland – from road racing to Gravel to trail. Thanks to ShadeTronic® the lenses adapt to changing light conditions in around 0.1 seconds and cover the S2–S4 range. The Size S variant is the more compact version of the Rev and, with its adjustable nose pads and temples, delivers a precise, comfortable fit. It also offers UV400 protection, polarized lenses and the sky tint with blue mirror coating, which enhances reddish details in high contrast – ideal for rapid light changes on Swiss roads and forest tracks. Each Rev is handmade in Switzerland and comes with a case and cleaning cloth. These features are documented in detail by the manufacturer and have been repeatedly verified.

Technical Details and Functions

The Rev uses an LCD-based system: photodiodes convert infrared radiation into electrical energy and thereby control the tinting of the display in the lens. This lets the glasses react without delay to changing brightness, entirely without a battery – practical for everyday use and long rides. The tilt angle of the frame can be adjusted as can the nose pads (two positions) and the temple ends, which optimizes contact and reduces fogging. The sky lens with blue mirror coating increases contrast for reddish details, while the polarization reduces reflections on wet asphalt, water or snow. With UV400 and tested standards including CE/EU 2016/425, ANSI Z80.3 and IP65, the glasses are engineered to be robust for sporting use. The total weight is around 40 g, which combined with even weight distribution provides a stable fit even on rough surfaces.

Use Cases and Benefits

The Rev Sky Black S plays to its strengths wherever light and shadow constantly alternate – for example on rooty MTB trails, in the Gravel flow through the forest or when changing direction quickly in urban traffic. The extremely fast tinting adaptation keeps the view steady and details visible, which noticeably supports safety and the sense of speed. For rides at dusk the base tint remains comparatively dark; for true night or twilight rides a clear spare pair is advisable. On road passes the polarization reduces glare from sun and snow, and when commuting UV400 provides reliable protection; the S2–S4 range is also approved for driving. Thanks to its adjustable geometry the glasses sit stably under modern helmets; the light sensor placed centrally at the top also works reliably with larger visors. These practical impressions were confirmed in independent tests.

Notes on Fit, Care and What's Included

The described S-Version (Small) is the smaller frame variant of the Rev and is suitable if you prefer a more compact coverage or if you fall between two sizes. The package includes a hard case and a cleaning cloth; for care, lukewarm water and a soft microfiber cloth are sufficient, aggressive cleaners should be avoided. For glasses wearers a suitable prescription clip is available, which your optician will fit individually. The Rev is fully functional down to –20 °C, which also makes it attractive for winter training and snow sports. Thanks to Swiss Made production you benefit from precise workmanship and durable materials – a solid choice for frequent female and male riders in everyday Swiss cycling.
