Without a doubt these are the best fitting, most comfortable under wear, right out of the box i ever bought. Just be careful the silk pair ran big. I'm a big guy bought xxl in silk they were too big. But the company (excellent customer service). Replaced with the large size, but i like a tight fit. If you buy them in cotton i went for the xl size. They are super comfortable I know where i'll be buying my under wear from now on. Plus they hold your package just right (because of the pouch built in). Buy these you won't be disappointed if you like this style. But arjen kroos make a ton of styles just pick the one you like.
