Fits great. Bought a 42US after talking with Jake I am 5’7”, 175#, with very athletic build. Dainese and Alpinestars always tend to be too tight in the chest, shoulders, and biceps. The RTS fits well with plenty of expansion panels and airflow. Just a tad long in the arms, but workable. Definitely take a look at this suit. Price is great and customer service is superb.
