The Hayabusa OdorResist rash guard is our best performing compression to date. It better protects your skin from abrasions, keeps your muscles engaged, it’s not see through and wicks away sweat, helping to control your body’s temperature. We used the famous XT2® fabric and doubled the amount of silver from our previous generation. This rashie uses silver, an old school tech that helps prevent sweat eating microbes from growing on it. In 2018, we marked a dozen years of making and improving our rash guards. Give it a roll, it’s worth it.
