Under Armour recently introduced the world's most innovative athletic evaluation improvement tool, stating "It's not a smart shirt. It's genius." Beginning last Thursday and running through today, more than 300 top prospects for the 2011 NFL Draft are participating at the NFL Scouting Combine in Lucas Oil Stadium in Indianapolis. Dozens of prospects, including Heisman Trophy winning quarterback Cam Newton and Alabama wide receiver Julio Jones have been wearing the Under Armour E39 compression shirt during their workouts. It weighs less than 4.5 ounces and is made from the same material as the rest of the company's compression-based apparel.
