Now that I'm selling my car, I can afford to buy a suit

Question is, shall I buy a 4 years old Sparco Sprint or a brand new Sparco Jade? They are about the same price (Sprint is slightly cheaper).

What's the main difference between them anyway? New Sprint costs twice as Jade so there must be something. Both SFI3.2a/5, I guess Sprint is lighter, and maybe looks a bit better, but what else?

Thanks for any advice,
Daniel
