Freeze part of mesh while sculpting?

As the title says, is there a quick and easy way to freeze a part of your model when scultping, so that that particular area can’t be sculpted on?

I saw a youtube video of a guy doing this but having to use vertex groups etc. wich is ofcourse an option, just want to know if there is an easier way?

Thanks

Lovely! But can’t really get it to work, so I’ll just get one of my friends over to hopefully fix it.

Thanks
