  • FlexFoam™ is a proprietary frame material developed by us. This material is even lighter than TR90, while also being highly elastic. FlexFoam™ allows for easy adjustments by hand, offering a more customizable fit and added convenience for users.
    Additionally, one of the standout features of FlexFoam™ is its buoyancy. Sunglasses made with FlexFoam™ can float on seawater, making them ideal for water sports or beach trips. This eliminates the worry of losing your sunglasses in the ocean or pool, adding an extra layer of functionality to an already high-performing product. The combination of lightness, durability, flexibility, and buoyancy makes FlexFoam™ a top choice for those looking for comfort, performance, and peace of mind when it comes to their eyewear.

  • Great question! Floatantium is now known as FlexFoam™. While the name has changed, the incredible technology remains the same. FlexFoam™ continues to provide the same lightweight flexibility and comfort that you've come to love. We made this change to better reflect the performance and versatility of our frames. So rest assured, whether you call it Floatantium or FlexFoam™, you’re getting the same high-quality experience designed for your outdoor adventures.

  • Standard for floating seawater:

    • Seawater temperature below 25°C
    • Seawater salinity above 36 PSU (Practical Salinity Units)

    Also, FlexFoam™ frame with prescription lenses may affect the floating performance partially.
