I watched the video that STG supplied. I have a similar build to Van, moreso a younger Van build (sorry). I am an avid gym-goer so I was worried about fitment. I decided to go with the 44/54. I am 6'0", 210#, and i have arms that are 20" around. This suit fits me real well. I am even able to fit my big legs in and have room and also have the liner in! I would say because of my build, i sit between a comfort and race fit in this size. I would recommend this suit to anyone wanting a quality suit at an amazing price. Again, this suit is more comfort than race fit, but with my build, its more 30/70. I love it!
