X-Bionic Energizer Shirt - Long-Sleeve
Here's what other sites are saying:
Maximize your workouts when you wear the X-Bionic Men's Energizer Long-Sleeve Shirt. X-Bionic's 3D-Sphere System technology diffuses your sweat evenly to prevent overcooling while its air-conditioning channel vents carry fresh air through the chest area for consistent temperature regulation. Lateral rib construction at the hip keeps the Energizer from riding up when you're on the move. Underarm sweat traps enhance evaporation and inhibit sweat pools from forming.
