This is how I felt about my MotoGP suit when it was new. I took it to Bickle to have it altered....he told me people would pay him to make their suits fit like mine already did. And he realized I felt like I was restricted and couldn`t breathe once the back prtector was in there, but said he wouldn`t take my $ until I raced for two weekends in it and returned to him. If I still had the same feeling after two weekends, he would agree to alter it.
He was 100% right. The new leather needed my sweat enzymes and some movement to stretch and form to my body in racing tuck, as well as molding to fit my back prtector on their just fine. It is now my suit of preference, and thank heavens I listened to John Bickle on that.
