Sexy Mens Underwear: Garrett Rau in Under Armour. Want more guys wearing Under Armour underwear? Well, here’s California male model Garrett Rau looking gorgeous in his Under Armour boxer briefs. In terms of modeling pics, we bet he can go mano-a-mano with MMA fighter and Under Armour celebrity ambassador Georges St. Pierre. More photos after the jump.

For other hunky men wearing Under Armour undies, check out MMA fighter Charles Dera and male model Sean Samuel [see below].

Black Model Hunk: Sean Samuel in Under Armour Sports Underwear. Seems like Canadian MMA fighter Georges St. Pierre will be in good company when he starts modeling for Under Armour sports wear. As we reported earlier, the sportswear company has hired Georges to be their image model/endorser.

Maybe they should hook him up with model Sean Samuel, eh? They would look good together, we think. Especially because they have the bald man look going for them. Want more black male models or celebrities? Go check out our post on Corbin Bleu.

Mens Underwear Update: Of course, Under Armour ain’t the only menswear brand that makes undies that look hawt, hawt, hawt on a man. For instance, this classic Calvin Klein is truly up there in the hotness scale.

Pink underwear for men is, of course, always pretty. Which is why, according to media reports, pink undies have become a bestseller these past years.

Now, a listing of hot underwear for men would not be complete if it does not include leather undies like this Modus Vivendi leather briefs.

Long johns are hot whether they are worn by a smokin’ Milo Ventimiglia as you can see in the photo below. Or whether your husband is wearing them to help keep himself warm during the cold nights of winter.

Also on the hot underwear for men list? This Superman briefs underwear!
