1 piece leather suit, you dont need perforation all over. Just in the chest area is fine. A fully perforated suit is big money.

If you do mostly street riding you should be fine with a 2 piece suit. Just make sure its got a heavy duty 360 degree zipper. Ive had a 2 pcs suit split open on me once.

I would stay away from textile crap, it will not do you any good pavement skiing. I have heard stories of the textile melting on the skin. It is better then a sweater lol

Another good thing to buy is a back brace, the ones that come with a lot of suits are not as great as the strap on ones
