HORSEFEATHERS photochromic glasses PROTON matt black/mirror green

Product description

One pair of glasses that can do it all. Horsefeathers Proton with photochromic lenses are designed for sports and everyday outdoor activities - whether you're out biking, running, hiking or just having an active day in the city.

The main advantage is the photochromic lenses, which automatically adapt to the light conditions. They darken in bright sunlight and brighten in dim light. This gives you optimal visibility without having to change lenses.

Perfect vision in every situation

The lenses increase contrast, eliminate glare, and maintain natural, true-to-life colors. Whether you're riding an open trail in the sun or diving into the woods, your view remains clear and legible.

The range of light transmission is ideal for changing conditions – from bright day to cloudy weather.

Lightweight frame for all-day comfort

The frame is made of durable and lightweight TR90 material, which is flexible, comfortable and ready for everyday use. Silicone nose pads ensure a stable fit and comfort even during prolonged activity.

The result is glasses that hold firmly, don't press, and can handle even the most demanding outdoor pace.
