    Optimized Throughout

    Inspired by the impeccable reputation the Onnit brand has earned in supplements, foods, and fitness equipment, the new Onnit Performance Apparel has been rigorously tested to ensure the highest level of quality is woven into each piece.

    Moisture Wicking Fabric

    Poly micro fiber mesh used throughout the performance line are hydrophobic and less likely to absorb liquid. The material allows for moisture to travel away from the body and evaporate.
