X-Bionic Bionic Vitalizer X-Boxer Short - Women's

For high-tech booty-cooling on a hot race day, look to the X-Bionic Womens Bionic Vitalizer X-Boxer Short. A team of Swiss textile scientists (yes, that is a career field) developed the Vitalizer X-Boxer to regulate your skins moisture and temperature during intense aerobic activity. An intricate system of wicking and moisture-storage fibers leaves a minimum amount of moisture on your skin to allow your body to cool. Built-in air-conditioning channels whisk away excess moisture beads and heat, cooling places like your lower back and inner thighs and releasing heat and moisture in places where it can evaporate away. The shorts boxer-style cut stays in place as you move, because nothing distracts like migrating underwear during an important race.
