KOO Nova Glasses

The KOO Nova Glasses are a frameless, single-lens cycling sunglass built for riders who want optical clarity and minimal weight without compromising protection. At 21 grams, the Nova sits at the lighter end of performance eyewear — present enough to shield your eyes, unobtrusive enough to forget they're there. Five distinct colorways round out a clean, stripped-back profile that works as well on race day as it does on a long training ride.

KOO developed the Nova's toric lens in collaboration with Zeiss, meaning the optical geometry is engineered to minimize distortion across the full arc of the lens — not just the center. The shatterproof Nylon construction provides 100% UV protection, and a hydrophobic treatment on both the lens and frame helps shed sweat and rain during hard efforts. Flexible temples are designed to handle repeated on-and-off use without losing their shape over time. An interchangeable nose pad system — with an Asian fit bridge option included — allows the Nova to sit correctly across a range of face shapes rather than defaulting to a single standard fit.

Design Benefits

1. Unobstructed peripheral vision: Removing the frame eliminates the structural interruptions a standard sunglass frame introduces at the edge of your sightline — a meaningful advantage when you're tracking riders in a bunch or navigating technical descents.
2. Zeiss-engineered optics: The toric lens geometry is designed to deliver consistent, distortion-free vision across the entire lens surface, so your view stays accurate whether you're looking straight ahead or scanning wide.
3. Fit adaptability: The interchangeable nose pad system — including an Asian fit bridge — means the Nova is designed to stay in place across a wider range of face shapes, reducing the mid-ride slippage that plagues one-size eyewear.
