Our patented, clinical-grade Hydro-Shield® technology stops underarm sweat from seeping onto outer layers. Through proprietary layering and stitching that creates reverse osmosis, sweat is drawn away from the skin and evaporated.
The Hydro-Shield® pads are seamlessly integrated into the shirt's design, requiring no adjustments.

Reviews
FAQs about our tees
Is the premium undershirt sweat proof?
No, the Premium Supima Cotton Blend Undershirt is an undershirt only — it does not contain the
patented Hydro-Shield
sweat proof barriers of our sweat proof undershirt.
Is Odor Shield™ technology safe?
Yes! Your body creates hydrogen peroxide every day to protect you from harmful microbes. Our Odor
Shield™ technology
harnesses the same power, combining nature's fundamental building blocks of water and oxygen to
provide a superior,
anti-odor treatment that is safe, non-toxic, durable, eco-friendly and perfect for daily use.
Unlike many products that use environmentally harmful materials like silver, our Odor Shield™
technology returns to the
ecosystem as it began, as water and oxygen, posing no risk to our planet or its inhabitants!
You're one eco-friendly decision away from harnessing the power of an unbeatable, natural defense
against odor.
Will the Odor Shield™ technology wash out?
Unlike other anti-odor treatments, our Odor Shield™ is a long-lasting, anti-odor technology that
stays put for at least
70 wash cycles.
