What to Look for in Athleisure Sunglasses

When selecting athleisure sunglasses, you have more flexibility than sport-specific requirements. There are, however, a few main factors to consider. In addition to being big-head-friendly, take a look at the criteria used by our Sports Opticians when choosing the best athleisure sunglasses for big heads.

Frame Material

No matter what the activity, a lightweight, comfortable frame is a must. This is largely achieved through innovative frame materials like TR90 nylon, Oakley O Matter™, or any other proprietary materials that boast durability and comfort.


To keep up with all your adventures, sun coverage is crucial. Found in many forms, all of these frames have wrap or generously sized lenses to give you the coverage you need. You'll be protected from harsh UV rays and have an unobstructed vision while enjoying the view.

Secure Fit

When you're on the move, don't let slipping sunglasses break your focus. Today’s lineup has strategically placed rubber grip so you don't have to worry about frame slippage and constant readjustments.
