I am 6'2" and 230lbs, I tried a X-Large and then got a XX-L instead. The problem with fit with me was neither the length or the waist, but the elastic around the thighs. I have larger thighs (though not fat), and the x-large was just to constricting on my thigh. The waist wasn't to tight on the x-large, but the xxl does fit just a bit better.

The material though is sensational, and my only complaints are the seam that runs down the front of short and the seams on the bibs, both necessitate wearing underlayers for me due to rubbing irritation.
