I am about 6'1 and about 175 pounds. I was wondering what size jacket i should get. I tried on my buddies 44 speed master, it fits pretty fine, but i notice it might be big for me. When i ride i can feel gaps around my stomach area when i bend over. When i stand the gap sort of moves to the back. I was wondering should i get a 42 instead?? ANother thing when i bend over the back of my collar touches my kneck
