I got these because I wanted something to wear while Jump Roping. I'm about 5'10 in height and my weight was about 165 pounds when I started jump roping. The size I got was Large and it a perfect fit. My only con to them is the Jacket which I would say should be 1 size larger than the Large. The jacket ain't really needed though, all you really need is the shorts/pants/t-shirt/long sleeve. The Jacket thing was just there.
