For all you tech junkies, the X-Bionic Women's Energizer Long-Sleeve T-Shirt hits the spot. When you're physically pushing the limit, the Energizer's fabric prevents dripping sweat and cools your body, so you don't overheat. Also, you won't have to fidget with your shirt as the lateral rib construction at the hips keeps the waistband in place. Feel free to run, jump, and skip without any issues in the formfitting Energizer.
