Poor lens material

Very great sunglasses and protection from sunlight however I should point out that the tint on the lenses is very prone to scratching under normal use. I used this product for less than a week when I started noticing the greenish tint on one of the lenses got scratched and chipped away. However tiny the scratch is it will make the sunglasses unusable especially if you mainly use them whilst driving. Poor lens material quality.

These are Ok. I hoped theydthbe as good as a previous, similar decathon "newfeel"pair which had excellent polarised gold mirrored lenses and brown tortoiseshell frames in a similar shape. They were the best sunnies I've ever had. These are no match! I wish they hadn't discontinued the others :-(

Not tightly fit

Maybe a bit large for girls

Amazing At This Price Point

This is a good option rather than going for the high end products. Serves the purpose of polarized glasses with uv protection. Quality of plastic can be improved a little bit, but great buy

Additional Product Information



  • 100% Polycarbonate


  • 20% Styrene ethylene butadiene styrene
  • 80% Polyamide 12


  • 100% Stainless steel


An anti-UV material, but what is it for? To protect your eyes from an invisible danger... UV rays. UV radiation is always present, in winter or summer, in sunny or even cloudy weather, and it can be harmful to your eyes and their contours. To preserve your vision, the lenses of our sunglasses are made of polycarbonate mixed with an "anti UV" material that protects you from the harmful rays of the sun (UVA and UVB).


The best for your outdoor activities! The polarized lenses intensify the colors and improve contrasts as well as the view of the terrain. They provide good protection and excellent comfort by only transmitting the light in one axis, while also protecting you from glare by blocking the rays that are reflected off horizontal surfaces (water, snow, etc.) The only downside is that it makes it difficult to read screens (phone, etc.) as the Polarized treatment lowers the brightness of the screens.


Classification of tinted lenses according to the ISO 12312-1 standard: - Category 1: lens with a light tint for reduced sunlight. - Category 2: lens with a medium tint for average sunlight. - Category 3: dark lens for strong sunlight (sea and mountains). Between 82% and 92% of visible light absorbed - Category 4: very dark lens, for exceptionally strong sunlight (high mountains). Between 92% and 97% of visible light absorbed

Good to know

Our lenses are made of polycarbonate, a material that is highly resistant to impacts but whose major weakness is that they are vulnerable to scratching. Bear in mind that even if your lenses are scratched, the UV protection does not decrease; The mirror effect is purely for aesthetic purposes. The same goes for the color of our tinted lenses. Whether they are gray, brown, or colored… you can choose your glasses according to your taste and you will still be protected, whatever the color.

Don't throw it away, fix it!

Our glasses will join you on your hikes. Your lenses may scratch over time. To help to repair them, our polarized lenses (reference 8655386) or non-polarized (reference 8655382) are available so you can replace them yourself quickly and easily. Our environmental approach at Quechua also supports making these parts available to you. Don't throw away, repair!

Frames created using a bio-based polymer

For the frame of these sunglasses, we use Rilsan Clear G850 Rnew, a polymer made from castor oil. This bio-based material is a real asset in our development process and is tailored to making lightweight and flexible frames.

More eco-friendly glasses frames

To reduce the environmental impact of our glasses, action can also taken on the material used. On the frames of these sunglasses, we have reduced the amount of varnish and paint, and everything is incorporated directly in the mold of the product. This is still not enough, which is why we are working to ensure that, one day, these sunglasses will be 100% eco-designed.



Product testing

All our sports glasses are tested in our DECATHLON laboratories and in conditions for which they were designed. The design teams, product managers, engineers, and designers make sure that our sports glasses are perfectly suited to their use in the field.

Storage instructions

The quality of your vision depends on taking proper care of your sunglasses. The case is essential! Keep your glasses in their case to avoid scratches, knocks, and crushing.
