Semi-rimless shields have been having a moment, and 100% throws its hat in with the Korbin, a shape built around the brand's 3DPlane Molded Lens. Instead of curving a flat lens into place, the semi-rimless design eliminates material for a lighter overall feel, with Grilamid TR90 material for superior strength-to-weight. The payoff is a big, uninterrupted view with the frame tucked mostly out of your sightline, which is exactly what you want when you're scanning the road or picking a line through a rock garden. It's a shield that reads as sporty without looking like a full-on aero helmet accessory.

What actually makes these work over a long day is the fit hardware. Air vents are built into the nose bridge and temples to promote air flow and reduce fogging, and copper-core temples offer long-term shape memory for a precision-adjustable custom fit. That copper core is the detail worth caring about — you can bend the temple tips to your head and they hold that shape, so the glasses aren't fighting you every time you put them on. Ultra Grip Rubber on the nose and temples adds a soft feel and secure grip even when you're sweating, which is the difference between glasses that stay put on a climb and ones that creep down your nose.

On the lens side, you get real protection and clarity, not just a tint. The injection-molded polycarbonate lens is impact-rated for shatter resistance, with a hard-coating lens treatment that increases scratch resistance, and it blocks harmful UVA, UVB, and UVC regardless of sun or cloud conditions. The interchangeable lenses provide 100% UV400 protection while repelling water, dirt, and oil with hydrophobic and oleophobic treatments, so a face full of spray or sweat wipes clean instead of smearing. If your rides run long or your storage is rough, the shatter rating and scratch coating are the specs that keep these usable season after season.... Read More
