Summit Strong™ Photochromic sunglasses are built for athletes who refuse to let shifting light conditions slow them down. Featuring a black frame and photochromic lenses, these sunglasses seamlessly adjust their tint, starting from completely clear and darkening all the way down to 5% VLT, offering unmatched versatility for everything from pre-dawn starts to full-sun exposure.

The clear base tint ensures true-to-life color perception in low light, while the deep darkening effect provides maximum glare reduction in bright conditions. Whether you’re moving from shaded trails to open roads or tackling unpredictable weather, Photochromic delivers the right level of protection exactly when you need it.

With UV400-rated, scratch-resistant lenses, these sunglasses shield your eyes from harmful UVA and UVB rays while maintaining peak optical clarity. Our SaurGrip™️ technology ensures a secure, slip-resistant fit, keeping them locked in place no matter how intense your adventure gets.

Awesome eye protection

Have owned these sunnies for about a week. Had a chance to use them a couple times mtb biking and road biking. Super impressed with the speed the lenses transition. The glasses stay planted on my face on the rowdy trails and when my front tire washed out. Highly recommend these. Best bang for the $.

Fit well, work great.

Frames fit me well and the lenses work great. I'll only use photochromic lenses from now on.

Summit Sunglasses

The quality feels great, the same (maybe better) than brands that are 3x the price. Unfortunately this style was too wide for my face, probably similar to Oakley's fit. Customer service was really helpful with an easy return, and I will definitely buy again if a smaller style comes out!

First set of riding glasses

Difficult for me to compare against other options as these were my first set, bur I love that they don't over darken and they dont ever seen to dog up. The fit felt unexpected at first but in the end they stay on well and are now very comfortable.

Would recommend
