Classy and Simple Sunglasses at a Good Price

In a previous life I would spend a lot of money on namebrand sunglasses only to have them last a season or so until they got scratched up. I bought these because they were a good price and I like the color of the outside of the lenses (blue/green). The black frame is nice and simple. They fit my face well and are great for winter days with sun on the snow. The arms have holes for adding a lanyard or rope for your neck--a nice touch. In a month I've used them all around and traveling and there are no scratches and they look great. Good find!

Great quality-price ratio

Stylish sunglasses with a large lens surface, light and space-saving when folded.

So Cool!!

These glasses look so classy! Who needs to spend £100 on a pair when you get the same for a quarter of the price. They are also look very hard wearing and could take rough handling, absolute bargain!

Cheapest polarising sunglasses I’ve ever owned

These are incredible value for money, and the build quality far exceeded my expectations. I’ve worn these all through the summer, including a weekend climbing trip, and I expect they’ll last for some time to come.

Additional Product Information


Lens: 100.0% Polycarbonate ; Frame: 80.0% Polyamide, 20.0% Styrene Ethylene Butadiene Styrene ; Screws: 100.0% 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 which protects you from the harmful rays of the sun (UVA and UVB).


The best for your outdoor activities!The polarised lenses intensify the colours 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 which are reflected off horizontal surfaces (water, snow, etc.)The only downside is that it makes it difficult to read screens (phone, etc.) as the polarising 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 colour of our tinted lenses.Whether they are grey, brown or coloured… you can choose your glasses according to your taste and you will still be protected, whatever the colour.

Don't throw it, fix it!

Our glasses will join you on your mountain walks. Your lenses may scratch over time. To help to repair them, our polarised lenses (reference 8655386) or non-polarised (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 mould of the product. This is not yet 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, 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.
