1. Measure ear to ear across the back of the head. (Tip: there's a tear-off measuring tape in the manual to help.)

2. Set the back strap to match.

3. Open the front straps to their widest setting.

4. Place Loop Cocoon™ baby earmuffs on their head. Avoid placing the strap over the soft spot.

5. Tighten the front straps until the FitGuide lies flat. Flat = correct strap tension. Don't go tighter.

6. Check that both ears are fully covered with no gaps.

That's it. You've got it.
