Unfortunately, whenever I bump into them, they take a tumble and land on the floor... Not good for lenses or electronics. I've devised a simple hook arrangement that locks my headgear securely in place, yet allows for "grab-n-go" removal.
Step 1: What You'll Need
1 "S" hook (large enough to go around the band of your headgear)
Step 2: Attach the Parts... Screw Them In Place.
Just make sure the open end of the hook faces forward and hang your gear the way I'm doing in the photo.
When you let go, the gear will swing down, rotating the hook upward, locking everything in place.
Getting it off is just as easy.
