Therefore, if you jump into the pool at first, these goggles will fog. After a couple of lengths, the fog will clear and you will be able to enjoy a long “fog-free” swim.

These are good at fog protection, but be patient. Like all goggles, allow the temperature of the water to match the temperate of the goggles and your face before you feel the anti-fog protection properties. As a general rule, you can expect to get at least three months of regular swimming from these goggles before you notice decay in performance. I have covered the basics of goggle lens colour and how to choose the right lens colour for your swimming conditions in this article, “ How To Choose The Best Swimming Goggles? (Handy Tips)“ Do The Speedo Futura Biofuse Goggles Leak? The swimming goggle lens colour you choose depends on the lighting conditions of your swimming environment.This Table Is A Review Summary Of The Speedo Futura Biofuse Flexiseal Goggles Are The Speedo Futura Biofuse Goggles Comfortable? A daily rinse in clean water keeps these goggles in good shape, but three months of regular swimming will lead to an upgrade. Are The Speedo Futura Biofuse Goggles Suitable For Small Faces? These goggles are fitted with anti-fog protection. This means that there is a thin anti-fog film on the inside of the goggle lens, which stops them from fogging up.

Goggles fog up because there is a temperature difference between your face and the water. Just like a foggy car window on a cold morning, until the temperature differential is balanced, there will be some fog on the inside of the glass. Because of the large and soft gasket on the Speedo Futura Biofuse Flexiseal Goggles, they are not prone to leaking. A design feature of the “Futura Biofuse Flexiseal” range is the large and soft rubber sealing gasket. The Speedo Futura Biofuse Flexiseal are very comfortable goggles. Of all the goggles I have ever tried, I have found them the most comfortable of all.

Try to avoid wiping the inside of the goggle lens with your fingers, as this will remove the anti-fog film protection. How Long Do The Speedo Futura Biofuse Goggles Last? I swim with these goggles every day, so they are exposed to a chlorinated pool for 45 minutes every day. I have found that after three months at this level of swimming, the fog protection is not as effective and the flexiseal gasket tends to get water marks and an aged look.

I swim in a public swimming pool with little natural light, therefore I have chosen the clear lens option for the best visibility in dark conditions.
