Coast Optics: High-Performance Vision for Every Trail
At Cassiopeia, we focus on brands that prioritize both peak performance and environmental responsibility. We feature Coast Optics because they represent the future of cycling eyewear—combining advanced optical clarity with a commitment to sustainable manufacturing. Based in Whistler and tested in some of the world’s most demanding terrain, Coast Optics creates performance sunglasses and accessories designed to handle the variable light and rugged conditions of the Boulder foothills.
Our boutique carries a specialized selection of Coast Optics’ most versatile frames, featuring bio-based materials and interchangeable lens technology. Whether you are navigating dappled light on a forest climb or facing high-noon sun on the road, our collection—including the Nita and Nita XL series—offers superior contrast and protection. We also stock essential accessories like Glacier Side Shields to help you customize your setup for maximum coverage and glare reduction in extreme environments.

-
Sustainable Innovation: Frames made from bio-based materials that offer the same lightweight durability and flexibility as traditional plastics with a smaller carbon footprint.

Photochromatic Versatility: Lenses that automatically adjust to changing light conditions, making them ideal for the transitions between sun and shade common on Colorado trails.
