...to traditional North American Ski? The Winter Products are very similar to traditional North American Ski Jackets, but they are used for snowmobiling.

What does snowmobiling mean? Does "they" refer to "the winter products"?

It means hooping on a snowmobile which is like a motor boat except for snow then flipping down a hill as you get trapped in an avalanche because you kept blowing your rape whistle because a wild bear was chasing you.
