Under Armour makes a very bold claim with their Boxerjocks – “You’ll Never Wear Regular Underwear Again.™”. Under Armour's longer length 9" Boxerjock offers extended leg coverage and performance-enhancing compression for the muscles. Boxerjocks are built from smooth, sleek high performance HeatGear 4-way stretch fabric, made to move with you and recover its shape immediately. Added to this is Under Armour’s signature Moisture Transport System, designed to wick moisture to keep you dry, and anti-odour technology to keep you fresh, while a mesh fabric fly panel aids cooling. Under Armour says The Boxerjock is a best seller for Under Armour season after season for one reason—because they perform. (03/12)
