Saxx Ultra Long John
I've had some the boxer briefs from Saxx and really liked them. The Ultra Long John is perfect minus one problemthe rise is too low in my opinion. I would like to have it come up further on my waist as it ends to not be as secure as some baselayers that do have a higher rise. The material is sick though, it is super-light and VERY breathable. The pouch for you junk is really what makes me overlook everything and keep wearing these every time I ride. I am 6'1", 180 lb, and have a 34" natural waist and bought the mediumand I can definitely say that large would have been too big. I wear the Saxx Ultra Long John for snowboarding and cold--weather running (layered under shorts).
