Under Armour makes a very bold claim with their Boxerjocks – “You’ll Never Wear Regular Underwear Again.™”. These are Under Armour’s mid-length 6\" Boxerjocks, built using flatlock seams from smooth, sleek high performance HeatGear 4-way stretch fabric, made to move with you and recover its shape immediately.  An articulated mesh crotch gives support and cooling. More fabric technology is present with Under Armour’s signature Moisture Transport System, designed to wick sweat away, while anti-odour properties help keep you fresh. Under Armour says The Boxerjock is a best seller for Under Armour season after season for one reason—because they perform.
