    Built by Hand and Backed for Life

    Costa sunglasses are assembled by hand from the highest quality material available by people who take great pride in their work. At Costa, they know they’re selling you a quality product so they stand behind it with a lifetime warranty against manufacturer’s defects.

  • Tough nylon and Hydrolite fused together to make the most hardcore frames.
  • The hinges are made of stainless steel to resist corrosion. And they are flexible so that they keep their shape and adjust perfectly when worn.
  • The corrosion-resistant alloy that Costa uses in their metal frames and rimless sunglasses is a super tough material called Monel.
  • Both of Costa’s Hydrolite and silicone nose pads are made to perform. That is, the more you sweat, the better they grip.
  • Wire core temples provide stability and durability that’s adjustable with a simple tweak for the perfect fit.
