The Nagai frameless sunglasses are made to move with you, whether you're cycling, running trails, or on the golf course. By stripping away excess material, they deliver ultra-light comfort and ventilation. Featuring an 8-degree curve, adjustable nose pads, and non-slip temples, they stay secure and comfortable through every activity.
The Amethyst lens suppresses direct glare while enhancing the texture and depth of white objects and landscapes, ensuring greater clarity. The balance of natural color and contrast makes it ideal for winter sports and alpine adventures, trail running, but also for golf, and helps you navigate bright, high-altitude environments with ease.
