The stylish goggles with sleek and hydrodynamic design are perfect for competitive swimmers and are FINA approved. They are equipped with arena's revolutionary Swipe anti-fog technology that lasts ten times longer than regular anti-fog protection. For perfect clear vision. For long. To reactivate the anti-fog treatment gently swipe the inside of the lenses five times while the goggles are in the water, once you see the first signs of fog. The hydrodynamic low-profile lenses minimize water drag and offer wide vision. Delivered with five interchangeable nose bridges for perfect customization to different face and nose shapes. The dual strap is easily adjustable at the back of the head and guarantees a secure fit, even on starts and turns. The goggles are equipped with UV protection and are PVC free. This model is available with clear lenses for low-light environments and for those who prefer maximum brightness, medium-dark lenses for all uses and dark lenses for bright environments or those who prefer maximum light shielding.
