Sizing Guide
Find Your Fit
AirFly is designed to fit any face — no nosepads means no single "size" dictates comfort. But frame width still matters for the best fit.
How to measure
Measure ear-to-ear across the back of your head (where the temples rest), or simply check how your current sunglasses/eyewear feel around the temples.
| Your measurement | Recommended model |
|---|---|
| Narrower / smaller face | AF-301BK, AF-301WV Wider frame, more coverage |
| Standard | AF-302WP (LUNA), AF-302SP (TERRA) |
| Broader face | AF-30X Wide-fit |

Getting the Perfect Fit
Names of Each Part
Before adjusting anything, it helps to know what's what.
Getting the Best Fit
The side pads can be fine-tuned in three ways — rotation, parallel shift, and angle — to match the width and angle of your own face. The more surface area of the side pad that's in contact with your face, the more stable and comfortable the fit.
When you're just getting started, it helps to check in a mirror how the side pads sit against your face as you adjust — it becomes second nature quickly.
How AirFly Fits On
AirFly is designed to spread slightly as you put it on — that's what lets it sit deeper and more securely.
Position It However You Like
Since AirFly has no nose pads, there's no fixed "correct" distance from your eyes — wear it closer or further forward, whatever feels right.
Adjusting Lens Height
High-Vibration Activities (Running, etc.)
For running and other high-impact activities, tighten the hold a little: bring the side pads and temples slightly narrower than usual, tucking them in, and always make sure the temple tips touch your head. The temple tips can also be bent vertically; angling them slightly downward behind your ears gives a more secure hold.

Troubleshooting
Common Fixes
Lens slips down / feels unstable
The temple tips likely aren't resting against the back of your head, causing the side pads to rotate. Make sure the temple tips follow the curve of your head and stay in contact — this stops the rotation and stabilizes the lens.
Side pads hurt — pressing in too far
The side pads may be sitting further inward than necessary. Try spreading them outward by 1mm at a time — even a small adjustment makes a noticeable difference.
Side pads hurt — temple tips aren't touching
When the temple tips don't touch your head, the side pads end up carrying all the pressure on their own. Rest the temple tips against your head to spread out the pressure — bending them slightly more firmly makes the side pads press more gently by comparison.
