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.
These goggles can be used over small glasses. Plenty of room inside these goggles and not as overly huge as some of the traditional over-the-glasses goggles.
If the tube stoe edge ever separates from the edge of your goggles, apply super glue and reattach the tube stoe edge.
