In my experience, these are slightly roomier in the crotch than other CK styles, but not to the point where you'll need to size down. The best thing about these, which you can't necessarily tell from the description or image (unless you use the hover-on zoom), is that they are a very fine mesh. As described, they are super lightweight and breathable, which is great for those of us who are prone to sweat down there. If you're looking for a comfortable, breathable brief that's great for exercise and general use, then these are a fine choice.
