Why we made Siena Sunglasses.
Built to celebrate and keep up with reigning IRONMAN® World Champion, Lucy Charles-Barclay, Siena is all style, all performance, and no compromise. This limited edition frame combines lead-the-pack engineering with off-the-field look.
CORE TECHNOLOGY
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-SLIP GEKO™ PADS
Proprietary formulation enhances fit and retention, relieves pressure points, and gets stickier when wet.
ADVANCED LENS COATINGS
Color. Contrast. Clarity. Our proprietary lens designs offer best-in-class optics with UV protection + anti-scratch, anti-reflectance, and hydrophobic coatings as standard issue.
SPRING HINGES
Rated to 25,000 cycles. Our precision hinge engineering means no loosening over time. Functionally they act like suspension while exercising and make for a more comfortable fit.
NO PRESSURE POINTS
Our GEKO™ grips eliminate uncomfortable pressure points.
