I ordered acording to the sizing chart. The chest and back shoulders fit great. The arms were to small in the forearm area. The straps for the elbow pads were in poor locations and made the fit even worse. I did not try the next size up as I was unhappy with the design of the product. I use my worn out 661 pressure suit from 4 seasons ago. And like it much better. Even though its beat and needs replaced. Also they say the back is removeable, they do not tell you that when you remove it the front has no straps to hold it in place. Just a poor design.
