Under Armour's E39 shirt looks mostly like a typical Under Armour compression shirt, which is to say, entirely unflattering on those of us who aren't professional athletes. But the E39 is actually a very different beast from the usual apparel, packing a triaxial accelerometer, a heart-rate monitor, and a breathing monitor. The days of simply clocking an NFL prospect's 20-yard sprint time are over--now coaches can see second-to-second updates on the player's internals, and even track the acceleration and deceleration of a player's individual strides.
Under Armour was the first company to convince athletes to wear skin-tight clothing during competition. Now they want you to sleep in it. The Under Armour Recharge is a compression garment designed to be worn after a workout.
The Recharge, available July 15th, consists of a long-sleeve shirt ($99.99) and full-length pants ($89.99) with targeted compression in certain muscular regions. Athletes are instructed to change into the suit within two hours after a workout, and to continue wearing the garment for a full twenty-four hours.
