I'm 6'2" and rotund and the XXL fit in a way that I never thought a pair of pants I purchased without trying on first possibly could. Definitely going to be buying more.
*edit* After a couple months of relatively infrequent wear, these have already developed holes in the between-thigh area where the fabric rubs together while walking. Although this happens to a lot of my pants eventually, this was a little too quick to justify a 5-star so I'm bringing it down to 4. For full information I'm most likely going to replace them with another pair of the same.
