I have several pairs of EW 0119 max light boxer .  This fits and feels like cotton, very light weight material, not much compression. does not hold shape as well as the more synthetic styles from ergowear.  The pouch on this style is very form fitting and creates a visible profile through some light weight pants.  some of their new styles have a wider pouch that does not stick out as much as these, but these support better IMO.  These breath really well.
 Here is a picture of how this cut fits ( this is the max mesh version) I'm 6'4" 200 lbs 34 inch waist and purchased Xl .
This underwear is not a novelty or gimmick. They seriously are a huge technological improvement in men's fashion. I encourage you to try a pair.
