Hero Strap attaches to the top ear protection area or goggle strap slot on each side. Some masks have more than one possible attachment point depending on brand & model, and  player preference based on what you feel is the most comfortable and safe.
 
*Make sure that the HS logo is facing outward and visible while wearing - not inside against your head - to ensure the clip is correctly attached to your mask. The goggle strap should always overlap the clip. 

Hero Strap is adjustable, so tighten or loosen as needed. In order for the strap to be most effective, position the strap in the middle of your head, not too far forward or backward.
