U.S. Sizing estimates are my own estimation. Please compare the measurements below with a pair of coveralls that fit you well. Returns for the wrong size costs both of us time and money.
Euro 46 - M/R. The chest measures app. 22" armpit to armpit or 44" all of the way around the outside of the chest measured from just under the armpits. Shoulders as measured from the outside shoulder seam to shoulder seam is app. 18 1/2". Sleeves measured from the outside edge of the shoulder seam to the tip of the sleeves is app. 24". Total length measured from the top of the shoulder to the bottom of the leg is app. 62". Inseam measured from the crotch seam to the bottom of the leg is app. 31" (note that with the way these will ride that will probably add 2" or so to the inseam).
