STEP 1: Position goggles into the eye sockets to determine if the goggles are comfortable. You should feel a slight suction.
STEP 2: Stretch head strap over back of the head to rest at a 45 degree angle on the crown of the head. Adjust strap so goggles are a firm fit. Tightening straps does not always prevent water leaking.
STEP 3: Ensure the nose bridge is adjusted correctly. Hedgehog nose bridges and individual size nose bridges are ideal for difficult to fit faces i.e. large noses, wide faces, high nose bridge.
