We can send your club sizing samples to try prior to ordering to make sure your happy with fit before you order. Fit of garments does vary. Typically in our range the top of the range Pro SL level has a tighter race fit. You should still be the same size but these garments are designed to be tighter (so again we strongly recommend trying before you buy). Our D2Z suits are wind tunnel tested for maximum results and performance and are designed to fit perfectly in the riding position. As such even standing up straight in these maybe uncomfortable. Any suits must be tried for size before you buy.
