in addition to Lendl's endorsement, Trion:Z ionic/magnetic necklaces and bracelets are worn by professional athletes from the NFL, NBA, MLB, INDY Car, Tennis and over 200 professionals on the PGA TOUR, LPGA Tour and Champions Tour.
Trion:Z bracelets and necklaces are made with a unique material called “STAYERS” which has minus ion-producing minerals woven into the fabric to counteract the positive ion build-up which leads to excess fatigue, heightened sensitivity to pain, and reduced focus and concentration.
Trion:Z bracelets can be purchased at Amazon.com.
