AeroArc Cap

The AeroArc Cap is exclusively designed for runners who wear glasses. Through precise ergonomic structures and aerodynamic optimization, it solves the common issues of traditional sports caps, such as pressing against eyeglass temples, causing ear pain, and leaving marks on the nose bridge. With approximately 44% of the global 680 million myopic population having a habit of running, traditional caps inevitably overlap with and press on glasses during prolonged exercise. The AeroArc Cap frees up temple space while maintaining a stable fit, delivering a burden-free and incredibly comfortable running experience for those who wear glasses.
The core innovation of the AeroArc Cap stems from in-depth research into the pressure zones above the ears and the motion trajectory of eyeglass temples. The sides of the cap feature a "crescent" curved structure, geometrically optimized through the "6910" Golden Ratio system:
69° Side Profile Angle: Frees up space around the ear region.
10cm Extended Curve: Enhances the wrap-around stability of the cap.
1.5cm Lower Edge Height: Creates a dedicated avoidance structure for eyeglass temples.
This design forms a pressure-free channel of approximately 1.5cm above the ears, ensuring the temples do not contact the cap during movement. It maintains a snug fit, achieving a perfect balance between zero friction and secure wear.
To accommodate the visual space and aerodynamic needs of runners with glasses, AeroArc Cap has developed the "13·7 Golden Brim System," which integrates anti-friction, low drag, and sweat-channeling capabilities:
13° Upward Tilt: Ensures a clearance of >2cm between the upper edge of the glasses frame and the brim. This specific angle achieves an optimal drag coefficient (Cd) of 0.38 and reduces the downward vision blockage rate to a mere 8%.
7° Slight Backward Arc: Tailored to fit approximately 90% of Asian head shapes, it secures a glasses clearance of ≥1.5cm. Simultaneously, this angle optimizes the sweat drainage path. Empirical data indicates that about 92% of sweat drips off along the brim's edge, significantly reducing the likelihood of sweat entering the eyes or smudging the lenses, thereby ensuring uncompromised visual clarity during exercise.
