Why we made Alto Fusion Sunglasses
Weighing in at just 15 grams, Alto Fusion is where elevated design collides with everyday performance. This ultralight titanium frame is paired with an acetate ring for a modern, twist—our sleekest metal silhouette where style meets substance. Think featherweight comfort, premium materials, and a fit that moves with you, not against you.
The sculpted temples are fully adjustable for a custom fit and lined with our GEKO™ grip for that locked-in feel, no matter how hard you go. Even the silicone nose pads are upgraded with GEKO™, hugging your face with a soft, grippy hold that stays put without pressure. And with our C3 Optics™, you’ll get the pop of color, contrast, and clarity that makes everything look just a little better.
Alto Fusion is a limited-edition release that redefines minimalism. With bold style and our signature performance DNA, eyewear has never looked - or felt - this good.
INNOVATION
FLOATFIT™ FRAMES
We obsess over every detail across design, engineering, and materials science to ensure your frames can keep up with anything you throw at them. The result is a frame that is extremely durable, lightweight, comfortable, and will stay on your face. We call this Float Fit, and we invite you to feel the difference.
NO PRESSURE POINTS
The silicone nose pads are more like pillows, embedded with GEKO™ for a secure, comfortable fit that eliminates pressure points.
PREMIUM LENS TECHNOLOGY
Our proprietary C3™ lens tech (stands for Color, Contrast, and Clarity) offers best-in-class optics with UV protection + anti-scratch, anti-reflectance, and hydrophobic coatings as standard issue.
NO-SLIP GEKO™ PADS
Our proprietary formulation relieves pressure points and gets stickier when wet. You’ll find GEKO™ Grip on the end of the temple arms to enhance retention, it’s removable for an even more minimal look.
