PositiveFibrix face softens impact and gives you lively rebound on off-center blocks, making back-glass defense feel super forgiving. It's 5 grams lighter than the stiffer Vertex models, so it moves fast at the net and won't strain your arm. Just watch full swings since that extra bounce can sail into the back glass, and it doesn't come with a Hesacore grip.
