Every part earns its place.
We obsessed over the parts you never think about: the nose pads, the vents, the arms, and especially the lens. Each one solves a problem runners actually have, from bounce to fog to glare. Nothing decorative. Everything does a job.

Most Innovative Lens Tech
The Infinity is our smartest lens. Photochromic, so it shifts tint with the sun: light in low light, dark in full glare. A permanent anti-fog coating keeps your view clear on the hard efforts, and it blocks 100% of UV.

Adjustable Nose Pads
Bend-to-fit nose pads you can tune to your face, so they sit secure and pressure-free no matter your nose shape, and hold through sweat.

Frameless Design
An open, frameless lower edge keeps the frame ultra-light and lets it flex and move with your face, for an unobstructed field of view and no pressure points.

Featherlight Arms
Ultra-light sculpted arms with grippy tips that hold without squeezing. No headache on the long runs, no bounce at pace.
Built to spec.
My running squad has three different head sizes and face shapes. We all tried the Re.flex Infinity and every single person got a comfortable fit from the flexible adjustable frame. That's impressive engineering.
Not having to think about your sunnies mid-run is the goal. Really glad they're staying put. Appreciate the review.
Wearing sunglasses for 12+ hours during a long trail event is a different challenge to wearing them for 45 minutes. The Re.flex frame is genuinely comfortable all day, no pressure build-up, no rubbing, no need to take them off.
Trail is exactly the kind of environment we built these for. Really glad they're coming through. Appreciate the kind words.
Everyone talks about grip failing when you sweat. The rubber grip pads on the Re.flex that hold harder as you get wetter are genuinely wild. Hottest summer track session I've had this year and these did not move once.
Everything in one lens was the idea with the Infinity. Really glad it's coming through. Appreciate the review.
Everyone talks about grip failing when you're sweating hard. The rubber grip pads on the Re.flex that actually hold on better as you sweat are genuinely impressive, hottest summer track session and these didn't slide once.
Really glad the Infinity is delivering. It's the full system for a reason. Appreciate the review.
Always struggled with sore temples and ear pressure on long runs. The Re.flex flexible frame fixed that completely. The Infinity lens is great for standard conditions and the whole thing is just really, really comfortable.
Everything in one lens was the idea with the Infinity. Really glad it's coming through. Appreciate the review.

FAQ
What makes Re. sunglasses different from other running sunglasses?
At Re., we start where most sports sunglasses cut corners: the lens.
While many performance sunglasses use cheaper AC (acetate) lenses to protect margins, we choose premium PC (polycarbonate) lenses across our range. They’re significantly more expensive to manufacture...and yes, they hurt our margins, but they deliver far superior optical clarity, impact resistance, and durability, which matters when you’re running in changing light, traffic, and unpredictable conditions.
We then design our frames around those lenses: lightweight, ventilated, and stable at pace, with features like airflow channels to reduce fogging and fits that stay secure without pressure. Everything is tested, refined, and iterated by runners, with real feedback from running communities, not lab-only assumptions.
The result is running sunglasses that prioritise vision, safety, and performance first, built for everyday runners who care about how their eyes feel at kilometre 2 and kilometre 20, not just how the glasses look on a shelf.
Do you offer warranties or returns?
Yes, we offer a 30-day return policy on all sunglasses. Additionally, all Re. sunglasses come with a 1-year warranty that covers manufacturing defects. We stand behind the quality of our products and want you to be completely satisfied with your purchase.

Are Re. sunglasses suitable for non-runners?
Yes! While Re. sunglasses are optimized for running, they are versatile and great for any outdoor activity, including cycling, hiking, and even casual wear. The combination of style, comfort, and performance makes them suitable for any active lifestyle. Our Adaptor Lenses and Photochromic lenses can even be worn for indoor activities as a form of eye protection…or just because they look fresh!
Do you have sunglasses for prescription lenses?
At the moment, we do not offer prescription-ready sunglasses, but we do offer insert frames for all of our models (excluding Re.balance frames) which are automatically included free with your order. These insert frames will need to be taken to our optometrist to have the right prescription fitted. We recommend to speak to your optometrist before purchase to confirm specifics and cost, we are happy to provide any details if required.
