I see a rodeo theme...I read that Price tried his hand at professional team steer roping in the off-season.
Edit: Some people have asked about the cross on the back of the mask. I didn't find anything about the cross on this season's mask in particular, but I found an article about his previous mask and it mentions that he always wants a cross. Here's what it says:
"The new mask, which Price debuted two weeks ago in the Habs' home opener, has two common themes amongst his previous head protectors - the CH logo on the forehead and a cross located somewhere in the art work.
This is a tribute mask that he wore some last season and in pre-season this year. Maybe since it's a tribute mask it's for special purposes.
