A new mask is not gonna solve the hat problem.
Loosen the harness and practice removing it while wearing the combo hat.
Make sure you lift the face mask chin out and then up with your left hand.
Once the harness is loose, a tight hat should stay on.
The goal is to keep the hat on, but don't get bent out of shape if it comes off.
Grab it with your right hand and place into your left hand along with the mask.
Try to refit the combo cap as tightly as possible and practice again.
Usually after a few hot games, the head band readjusts to fit your crown.
If that doesn't work, purchase another plate hat one size smaller.
Keep the combo hat for bases.
