Engineered for the Runner Who Wants Less

The X365 Sunglasses strip away everything that doesn't serve your run. No frame around the lenses means no weight pulling down on your nose and no rim blocking your peripheral vision. What's left is pure performance: polarized lenses that kill pavement glare, UV400 protection for your eyes, and a fit so light you'll check your face to make sure they're still there. The grip-coated nose pads and temple tips lock in harder when wet — so the lighter your frame, the tighter the hold.

FAQ

The X365 is our frameless design — no rim surrounds the lenses, which means less weight on your nose and a wider field of vision compared to framed styles. It uses the same polarized lenses and grip-coated fit as our other models, but in the lightest possible package.
Yes. The X365 uses high-quality lens material and reinforced hinge points. Frameless doesn't mean fragile — it means we removed unnecessary material around the lenses, not from the structural elements. They're built to handle daily training use.
The X365 is ideal for runners and cyclists who prioritize minimal weight and maximum field of vision. If you find framed sunglasses too heavy or restrictive, the frameless design solves both issues. They're also popular for triathletes who need quick transitions.
Absolutely. The sleek, modern aesthetic works for driving, outdoor dining, and casual wear. The polarized lenses make driving particularly comfortable by cutting dashboard and road glare.
