“I mean, probably the best thing I can say about them is that I put them straight on and forgot about them... You know, if you’ve got nothing to report, then it’s probably good news.”
Sam Appleton, Professional Triathlete
“No, not any movement. Super comfy, lenses are clear... They’re really light, and I just bent the ends in slightly (AdaptX™ Temples) and they stuck exactly where I put them… not a single tiny bit of movement at all, even though I was throwing water at myself… it’s impressive.”
Luke Tasker, Professional Triathlete
"Impressed is an understatement. I love nothing more than a company run by real people, who live and breathe sport, looking to disrupt what some might consider a saturated space. Initial impression is that these are on par with... which I've used since 2011."
Andrew Talansky, Ex-Tour De France Cyclist
"Glasses were awesome!!! Used them during a workout so I got to test them at speeds faster than an easy run and I really enjoyed them... super light, stylish, and most importantly comfortable!"
Rocky Hansen, D1 Runner Wake Forrest
"Just wanted to let you know your glasses are phenomenal! The lenses are soooo good"

FAQ
AdaptX™ is the core difference. The temple arms are bendable titanium that conform to your head shape and hold there. Most sport frames are molded plastic sized for one face, which is why they slip when you sweat and pinch when you don't.
Sender Air™ also uses a high-contrast tinted lens tuned for outdoor sport, a slim profile built around helmet straps, and an adjustable nose pad that holds at speed.
Our lenses are not polarized — and that's on purpose. Polarized lenses block horizontal glare, which is fine for everyday wear but flattens depth perception when you're moving. You lose wet patches on the road, shadow detail on trail, and surface reads on the bike. SendSight® uses a high-contrast tinted lens with full UV400 protection built to sharpen the ground in front of you, not flatten it.
Yes. Our lenses are made of optical-grade shatter-resistant and impact-resistant polycarbonate — built to hold up to cycling, running, triathlon, mountain biking, pickleball, tennis, and any outdoor sport you put them through. The Sender Air™ is performance eyewear and not rated for construction or industrial use.
The silver mirror is the outside anti-glare coating. The base lens underneath is the most neutral of the four — almost no color shift, just clean dimming. What you see is what's there. At 14.03% transmission it's matched to the Blue but renders true color across the board. The most versatile option if you don't want the lens telling you what to look at. Outside: clean silver flash, the most understated of the four. Inside: a true-to-life view.
Best for: anything. Daily driver, road and gravel, running, lifestyle wear, travel, anywhere accurate color matters — photography, navigation, reading signage, work-to-trail crossover.
The Sender Air™ comes with:
- A protective hard case
- A microfiber pouch for cleaning
- A Lifetime Guarantee
- SendCare™ Replacement Guarantee
Yes. You have 30 days from delivery to make sure Sender Air™ is right for you. Try them on at home, move around, see how they sit. If they're not the fit you want, send them back — no return shipping charges, no restocking fees, no friction.
A prescription lens program is in development out of our San Diego optical lab. We'll announce when it's live. For now, Sender Air™ ships in our standard non-prescription contrast lens.
