Spy Optics Megalith Snow Goggles A low-profile frame with high-profile style. The Megalith is a retro-inspired goggle that provides crystal clear views to the edge of your peripherals. From afternoon sessions to full days on the hill, this goggle packs ultimate comfort into a badass frame with a cylindrical lens and a helmet-compatible fit. The sharp edges and beveled details give a nod to their single-lens sunglass counterpart, the MONOLITH. Equipped with SPY+'s therapeutic HAPPY™ Lens and made with 30% plant-based materials, the Megalith has checked the vibe so you can focus on the ride. SPY+’s Happy™ Lens is the foundational technology the brand offers across all its sunglass lenses, but it’s far from basic. Happy™ is SPY+’s proprietary technology designed to not just protect eyes but also boost mood and alertness by harnessing the beneficial aspects of long-wave blue light. Spy+ Happy™ Lens is available in non-polarized options in a multitude of tints and mirror options.
