## React Rev Sky Black S

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.
