Overview

KOO Nebula Sunglasses are a frameless, mono-lens sunglass designed for athletes and high-output riding. The frameless layout keeps the lower field of view completely open, while the lens shape and temple design are built to stay stable when you’re moving fast or riding in an aggressive position.

Lens & optics

Nebula uses a Zeiss® nylon toric lens designed for clear, panoramic vision with low weight and a curved profile for wraparound coverage. KOO lists the lens as anti-scratch and compliant with common eyewear standards (ANSI Z80.3, AS/NZS 1067.1, ISO 12312-1), and replacement lenses are offered in both regular and photochromic versions depending on your riding conditions.

Fit & stability

At just 21 g, Nebula is built to disappear on your face. A wraparound temple shape supports a secure, no-slip fit, and interchangeable nosepads help fine-tune comfort. The packaging kit includes a Low-Bridge nosepad for riders who want extra support or a different fit profile.

Serviceability

Nebula is designed around lens interchangeability—use a different tint for bright days, or swap to photochromic for variable light. Lens colorways have different VLT and filter categories, so you can match the lens to your typical conditions.
