Head has developed a synergy of two different silicones that ensures comfort and performance. The softer material, which is in contact with the skin, produces a better seal, whereas the more rigid silicone is used to create a stronger structure where the goggles are subject to mechanical stress.

The exclusive RAS buckles are applied to the most rigid silicone, supporting the secure tension of the head strap and preventing deformation of the lens frame.

The RAS buckles are positioned closer to the head, reducing water resistance and vibration.
