Curved lens technology delivers expanded peripheral vision for clear sightlines during training and lap swimming while titanium reactor photochromic lenses adapt tint to changing light. The Advanced Ultra Fit frame uses high-grade silicone for a softer gasket seal and even pressure distribution, improving comfort for long sessions. Anti-fog coating and built-in UV protection maintain clarity and eye safety outdoors and in indoor pools. Quick-adjust straps and a low-profile split strap provide a secure, customizable fit in both regular and smaller profiles.
