I've tried several models through Google searches and Goodwill has benefitted. It's been an expensive and disappointing exercise. If they support, they don't breath, and vice versa. Asian sizing does not work for me. The latest option is the ExOfficio brief, which works on all fronts except cup size. Also, I find that boxer briefs work better to avoid chaffing. I rode some rough stock in my youth and have some scaring that takes up extra room. Also, breathable fabrics tend to stretch out and lose support. I guess you guys aren't so afflicted. Lucky you.
Dr. recommended an athletic supporter over underwear, but that is way uncomfortable. Duluth Trading has a new breathable design that seems to have a seam sewn in for support, but look small in the "bullpen" in the site photos. I may try one pair to see how they work. The buck naked model is nice fabric but absolutely no support. I have like a dozen of those in a box somewhere.
