Product Description Offering an almost unmatched combination of comfort, touch and feel, this newer version of XCel adds a durability upgrade to Babolat's time-tested original recipe. The increase in durability will allow stronger players with longer strokes to enjoy maximum playability. While this string has more than enough pop for players with shorter strokes, the control is actually quite good for the breed. Suitable to all ability levels, this one is a genuine treat for any non-poly player who wants to experience one of the most responsive multifilaments on the market.
