I have used Rip It masks on every helmet my DD has owned. I am sure it will fit, but some are easier to install than others. I have never installed one on a Worth Liberty, but if I had one, I'm sure I'd find a way. You probably will need to drill new holes somewhere around the ear holes, so be carefull about drilling into the padding. Try to move it out of the way or find a spot without padding so you don't ruin it. Sometimes you may also have to bend the mask a little to fit properly, but thats no big deal. Measure and mark hole locations several times before drilling.
Of coarse you may get lucky and the factory holes be in the correct location, but I never have.
