The Nike Legacy Goggles are designed for competitive swimmers. They feature a mirrored coating on the lenses to reduce glare and block harmful UV rays. The goggles are FINA-approved and have a curved lens that enhances peripheral vision and clarity. The Nike Swift Track nose bridge system makes it easy to get the perfect fit, and the curved back clip fits comfortably against your head. The goggles are made from BPA-free and latex-free materials.
