Replying to List of Things to Tell my Parrents When Trying To Convince Them To Let Me Buy Jiberish?

So I want to buy some Jiberish, But my parents confront me with the question of why buy a hoodie just because it has cool abstract designs and a sick fit for 80+ dollars? I know some of their hoodies are cut and sew witch lasts longer, and have to zipper that comes up higher like a jacket. But is it like Semi Water Proof and Wind resistant? Like the Line Static hoodie? Because if it is just cotton it would get soaked if you took a gnarly fall into some deep powder. So what Is Jiberish's Material i guess is what i am asking and what are the cons that makes it good for skiing?
