FlexZ Goggles Strap Adjustment
To adjust and set your elastic strap on your Flex Z goggles, first pull the strap to your desired length. Make a double-hand overhand knot, followed by a single overhand knot.
Trim the excess with scissors and lightly melt the edges of the ends of the outer sheath of the strap to keep it from unraveling.
