These collapsible square sunglasses combine functional engineering with urban aesthetics. The transparent-to-orange gradient frame transitions smoothly from subtle daytime accents to bold style statements. Flexible hinges allow seamless folding into compact form (coin-sized when folded), while maintaining structural integrity through 15,000+ cycle testing.
The dual ventilation channels along the temples work synergistically with the foldable design - airflow circulates effectively even during compressed storage. Soft-curve temples adapt to various ear contours without slippage.
Features ✓ Patented tri-fold mechanism with scratch-resistant hinges ✓ Gradient-transparent frame with brown UV400 lenses ✓ Ventilation-integrated folding architecture ✓ Pressure-free ear grip with 12° adjustable tilt ✓ Storage-friendly 1:3 size reduction when folded
