Coanda Fusion’s lightweight, hydrodynamic design fits perfectly and flows through the water with zero drag, so your only focus is going big.
How to Measure Your Head for a Helmet
-
Prepare a Measuring Tool – Use a flexible measuring tape or a piece of string.
-
Position the Tape – Wrap the measuring tape around your head, approximately one inch (2.5 cm) above your eyebrows and ears, ensuring it encircles the widest part of your head.
-
Read the Measurement – Note the measurement in centimeters (cm). If using a string, mark the length and measure it against a ruler.
-
Repeat for Accuracy – Measure at least twice to ensure consistency.

The streamlined, COANDA EFFECT design allows HYDA Helmets to move freely through the water for zero-drag duck dives and wipeouts. It also keeps the helmet very lightweight on your head and neck, so you forget you’re even wearing it.
ENERGY REDUCTION TECHNOLOGY™ features soft, plush, polymer pads that add rotational and linear impact energy protection against brain injuries, even at low-impact levels. The strategic pad design allows for fast water drainage after submersion.
INSTAFIT offers instant customization in key zones for a wide range of head shapes and sizes for a perfect fit, every time. This dial-in fit system is also easily adjustable on the fly, even while sitting in the lineup. (If your helmet doesn’t fit perfectly, it doesn’t protect.)
FIDLOCK’s patented magnetic chinstrap lock system ensures a quick and secure connection that can be fastened with one hand and doesn’t accidentally disengage…even during the heaviest wipeouts.
