Browning teamed with VisaEndurance® to offer the finest in scent control fabric. NTS (Next To Skin) features OdorSmart™ with VisaEndurance antimicrobial technology designed specifically for base layers. Rather than wear less reliable activated charcoal or less breathable, heavier fabrications, OdorSmart features patented encapsulated silver ion technology that inhibits the growth of odor-causing bacteria on the garment to prevent body odors. The silver ions work the entire life cycle of the garment, and do not lose effectiveness after repeated washings. Additionally, the fabrics themselves are highly wicking to move moisture to the outer layer where it quickly evaporates to keep you dry and comfortable instead of wet and clammy.
