I was thrilled with the fact that I could wear both of these without adding any amount of bulge under my jeans. I started out with the base layer of this Gregg Homme Joxx jockstrap…amazing for the sexy blue pouch, but more importantly, hot with the X cross on the ass in addition to the regular jockstrap straps. 
After that I slipped into the turquoise Andrew Christian long johns. They are super soft. Super comfortable. Super easy to wear. I love they way they feel on. They also have the great pouch in the front…not as hang free when you’re wearing a jockstrap underneath, but the concept is there. 
Layering…just one way I stay warm during Frigid February…or in any of the cold months!
