FRAME QUALITIES AND OPTIONS

Costa offers frames to meet everyone's needs. Customers can choose a frame based on color, hypoallergenic materials, durability, lightness, cost and uniqueness. Each frame offers its own performance advantages and style features for eyewear that fits every occasion.

Co-Injected Nylon Frames

Our nylon frames are tough and durable, with more color options manufactured using the environmentally friendly bio-resin process. TR-90 nylon is a premier material for sports and performance frames as it is resistant to heat and cold. Though it is flexible, it is still durable. Nylon is easily molded into wraparound and other shapes.

Acetates

Best for when you're not active, acetate has a warm, luxurious feel and allows for very rich color layering which creates vibrant, unique patterns. Made from tree pulp, acetate is a renewable source that is naturally hypoallergenic and can be adjusted for your best fit. Acetate is special because it molds to your face over time, giving it that fitted suit, worn-in jeans, leather sandal feel.

Titanium is as strong as steel but lighter weight, making these frames perfect for sports. Though titanium is one of the strongest metals, it reverts back to its original shape even after exerting pressure. Titanium is often used in prosthetics because it is hypoallergenic and corrosion-resistant.

  • PERFECT FOR SPORTS

INNOVATIVE SWEAT MANAGEMENT SYSTEM:*

Costa Sunglasses Ventilation

Ventilation

  • New ventilation ducting allows airflow through the end piece of the frame, which helps to keep you cool, reduces lens fogging, and works in conjunction with the sweat management template channels. **
  • Nose pad ventilation also available on Diego,Broadbill and Tico.
Costa Sunglasses Sweat Management

Sweat Management

  • Channels run the length of the temple that enable airflow from the vents to cool, wick away sweat and moisture, and drain through the openings on the temple tips.
  • Thinned-out inner bottom eyewire tucks closely into the back surface of the lens, which allows sweat and moisture to drain down the back surface of the lens and off the bottom of the frame.
  • Textured Hydrolite® nose and temple pads help manage sweat and heat - and provide a secure fit and all-day comfort.

*Patent Pending. **On Diego and Slack Tide
