Defender HF VestRiding a hydrofoil on any type of surf craft in any condition can go sideways quickly, making an impact vest mandatory equipment for most foilers. The Defender HF Impact Vest has been designed to give you gladiator level protection from a potentially injurious board or foil strike to the torso. The padding on the Defender HF Impact Vest is logically located to allow for unobtrusive paddling and smooth integration under a kite or windsurf harness.
