Why would someone want underwear made of bamboo? It may be for ecological reasons, or for comfort. No matter what the reason is to wear them, the good news is that bamboo is getting more and more popular as a fabric, and for that reason there are more and more choices available to us when it comes to bamboo clothes, and that includes underwear.
I don’t know how comfortable they are, but these look good to me:

Of course, the big question when dealing with men’s underwear is “boxers or Briefs?”
