Made with a lightweight C5 alloy frame Oakley's Polarized Spike Sunglasses are a full metal alternative to Oakley's O Matter Gascan without any extra weight to weigh you down. We ordered a bunch paired with the polarized iridium lenses to minimize glare from wet streets rolling waves and bright snow. Oakley's big peripheral lens design features a distortion-free plutonite material that's geometrically shaped and refined through Oakley's High Definition Optics (HDO) to maintain the same exceptional visual clarity through all angles of view even at the far edges. Cheap sunglasses with wrap designs usually bend light rays and distort your vision along the edges so you ignore the blurs and squiggles until something catches you off-guard. We like our Spikes for casual urban adventures in bright sun (especially at the beach) but the grips on the ear stems help these durable sunglasses hold their own through moderate-impact activities.
