I'm looking to order the below one piece, however before ordering I'd like input on which size. I looked at the sizing chart, however because im skinny i'm debating which size to get. I'm 5'11.5 and only 130-135lbs. I'm leaning at size 52 EURO , any advice from someone my size? http://www.motorcycle-superstore.com/1/1/42/11487/ITEM/Alpinestars-SG-1-One-Piece-Suit.aspx
