Aratac all natural chamois over grip.  Use it to increase the thickness of your stick handle or improve you grip in damp and humid conditions.  We recommend dampening (not soaking) the over grip before wrapping the stick.  This will help the over grip tighten and hold on to the stick as the over grip dries.  Some studies suggest a tight over grip will add power to your shots....  We have not been able to verify those results ourselves but your experience may vary!
