The sweat we naturally create during physical exertion doesn't smell but it creates bacteria that can smell. Gladiodor® and Polygiene® garment odor control from Patagonia work in multiple ways to fight this buildup. First, it stops the growth of odor causing bacteria and fungi by drawing them onto microscopic "spears" due to a pull caused by their molecular makeup. The garment is also infused with particles of carbon that fight odor by absorbing bacterial compounds that produce it. Baselayers equipped with Gladiodor® or Polygiene® stand up to multiple uses without the need for repeated washes, extending the life of the fabric.
