How does Odor Shield™ technology work?
Odor Shield™ is a natural, non-toxic solution based on hydrogen peroxide that eliminates 99.9% of bacteria in the fabric. Body odor is caused by bacteria breaking down sweat on the skin, so removing the bacteria at the source stops odor before it starts. The technology is infused directly into the fabric and holds up through at least 70 wash cycles, so you're not constantly replacing or retreating anything.
Does this shirt also block sweat marks?
No. The anti-odor undershirt is designed specifically to fight odor, not prevent sweat from showing through your outer layer. If underarm sweat protection is what you need, the sweat proof undershirts with Hydro-Shield technology are built for that. Many people wear both: the anti-odor shirt for everyday freshness and the sweat proof shirt on days when they need full underarm coverage.
What makes Supima cotton different from regular cotton?
Supima is a premium-grade cotton grown exclusively in the USA, with extra-long fibers that are softer, stronger and more durable than standard cotton. Here it's blended with MicroModal, a fine, lightweight fabric known for its silky feel and breathability. Together they create a smooth fabric with a slight stretch that's comfortable enough to wear directly against the skin all day.
How should I wash this shirt to keep Odor Shield™ working?
Machine wash in cold or warm water and tumble dry on medium heat or lower. With normal care, the odor-fighting properties are designed to last through at least 70 wash cycles.
