At the recommendation of my close personal friend Dave, (you have to be a close personal friend if you make a recommendation like this) I got a pair of under armour underwear. He claimed it was the best underwear ever.
The last time I got a recommendation like this is from my close personal friend Cris (great guy). He recommended silk boxers. Now while silk boxers are nice I find they tend to ride up on you. I'm by far more a fan of boxer briefs because, and I hope this is delicate enough, it allows your boys to roam, but still feel supported.
So I get a pair of these under armours (not under roos). And I gotta hand it to Dave. It's the best pair of underwear ever! Soft like silk, but yet the same stretchyness of cotton. They are expensive though..I plan on having them on my christmas list.
