Mach 1 : Tempête

Fits very well, clear vision, light and hold perfectly on the head,

Love the glasses, look good and work well, very comfortable, removes the glare of the sun.

Ngl, I was looking for a pair of quality riding glasses without the big brand price, and these absolutely delivered. They're comfortable and stay on my face no matter how sweaty I get, or how bumpy the road is under me.
On top of that, the violet tint is excellent for different light conditions.
I'd happily recommend these to anybody that needs a pair of sunglasses that stay on their face, and don't make the trail too hard to see.

Protègent les yeux

These Summits manage to get 70% of the quality of the other big brands but for 20% of the price.
Used to have an Oakley Radar EV before and the Summit's frame have noticiable lower build quality, but they still feel good and are significantly better than any cheap Chinese options. I don't expect these to last for over 10 years like my Oakley but they feel durable enough for at least 5 years of abuse.

The lenses are the biggest question mark for me. They do a great job blocking the sunlight as expected, but they feel more fragile than I'd like. They feel more flexible than they should and the reflective coating on them are not too confidence inducing. I don't know if replacements are available but it would give me some peace of mind if I could buy extra lenses.

The nose padding is fantastic and it is adjustable in case you have an asymmetrical nose.
The rubber padding behind the ears feels good while riding, but I feel some irritation when removing it after a 2h ride. Your mileage may vary.

With all that said, I'd still absolutely recommend these glasses. They definitely punch above their price range and so far I'm happy with my purchase.
