Try to casually rock professional-grade equipment, and people will ridicule you for dressing like it's Halloween -- resulting in you crying, and throwing away a perfectly good fireman's hat. For serious performance with savvy style, grab Costa Del Mar sunglasses.

Out of Daytona Beach, Costa's spent the last 25 years pioneering polarized lens technology for the likes of Dennis "America's Cup" Conner, Jacques Cousteau, and F-16 fighter demo teams, who needed the solar-tech to cut blinding glare during games of shirtless beach volleyball. Whether you go with their "Core" models or the more laid-back "Shore" line, their premier glass lenses offer super-truthful optical performance, blocking eye-fatiguing yellow light while enhancing definition and color perception in other ranges; meanwhile, their new Silver Mirror lenses maintain polarization even in low light, so if you choose to be a sunglasses-at-night jerk, you won't be a blind jerk. The 11 new frame designs are highlighted by the "Permit" with broad eye coverage, a no-slip rubberized surface, and vents for defogging; the "Placida", a hybrid big-eye/aviator with neo-70s details; and "Cudjoe", matching hi-res lenses with the nutter-swagger of Magnum PI.

All the shades are extraordinarily sturdy, and come with a lifetime warranty -- which is a while, considering your aversion to saving people by kicking in burning doors.
