Ive only worn them (I purchased two belts, navy and gray) a couple of times and they seem fine. In terms of pant size, for reference, I wear a 33 in most jeans and 34 in Nike golf shorts, and the medium size belt fit just fine. The D rings feel sturdy and the belt color seems to hold up under humid conditions (I have had a canvas belt bleed its color onto my garments previously). As mentioned, Ive only had limited time with these, if they continue to perform in the same manner, I have no hesitation going to a five star rating!
