In A Multi-Year Endorsement Deal, St-Pierre Will Be Featured in Under Armour’s Upcoming Campaigns Showcasing Fitted ColdGeara(R), Underwear, Recharge(TM) Suit, and New Coreshort product

BALTIMORE, Nov. 5 /PRNewswire/ — Under Armour, (NYSE: UA) the Baltimore-based leader in performance apparel and footwear, announced today it has signed Mixed Martial Arts (MMA) Welterweight Champion Georges St-Pierre to a multi-year endorsement deal. Under the terms of the agreement, St-Pierre, the 2008 Sportsnet Canadian Athlete of the Year, will serve as the face of Under Armour’s Underwear, one of the company’s most popular items, and will be featured in its multi-platform media campaign beginning this holiday season.

St-Pierre, known by his fans as GSP, will be featured in imagery displayed in Sporting Goods stores across North America, outfitted in Under Armour’s ColdGear®, performance apparel designed to protect athletes in cold temperatures. Beginning in spring 2010, St-Pierre will become the face of Under Armour’s long-time top-selling BoxerJock® and BoxerBrief Underwear and will serve as one of the primary faces for Under Armour’s Recharge(TM) suit, a suit designed to re-energize your body, promote muscle repair and reduce swelling following a workout.

“It is quite an honor for me to represent Under Armour. I have always appreciated the quality of their products, and to be partners with them is a dream come true,” said St-Pierre.

“Not only is Georges one of the biggest stars in one of the fastest growing sports in the world, but his dedication to training and making himself the best at what he does aligns perfectly with our Brand’s mission to make all athletes better,” said Steve Battista, Under Armour Senior Vice President, Brand. “When we found out that he was a fan of ours, we jumped on the opportunity to bring him into the Under Armour family.”

“Georges St-Pierre’s continued success in MMA, his character and integrity, and his wide-reaching fan base make him a terrific brand ambassador for Under Armour, which, much like GSP, has become one of the foremost brands in sports in a short period of time,” said Howard Nuchow, Co-Head, CAA Sports, which represents St-Pierre in conjunction with Shari L. Spencer, President of GSP Enterprises. “Pairing GSP with Under Armour is a testament to the explosive growth of MMA, and the popularity and cultural relevance of its top fighter, among consumers worldwide.”

New for spring 2010, Under Armour has joined forces with Coretection Products Ltd. to bring state-of-the-art patented technology to athletes for all sports around the globe. St-Pierre will be prominently featured in in-store imagery highlighting the new Coreshort compression product. The Coreshort product works to stabilize the core without obstructing movement. The unique technology creates efficient movement through the core, activating stronger motion and more explosive propulsion. Available in two styles; the Coreshort product will retail for $44.99 and the Coreshort Pro product will retail for $59.99.

Under Armour, the originators of performance apparel, has transitioned athletes into moisture-wicking apparel since 1996. Under Armour products are sold worldwide and worn by athletes at all levels, from youth to professional, on playing fields around the globe.
