Sustainable style and advanced performance define these men's sunglasses from Under Armour. The navigator shape is perfect for everyday looks, made of 50% recycled materials for uncompromising style. Even the TRITAN TR18 lenses are sustainable, and even more protective in their polarized version. They offer maximum freedom of use and durability thanks to a prescription-ready front, auto-locking hinges, non-slip rubber inserts and an XL size.
