Overview

Head Hawk features Crystal Core technology - a pliable inner core surrounded by a firm outer shell. This creates a string that is firm enough for exceptional control but muted enough to reduce harsh vibrations. "A soft, plush feeling string with a more deadened, controlled response" that feels very connected to the ball. Despite being low-powered, it's very soft and never uncomfortable. Allows players to really swing out on shots without fear of overhitting. Great value at $10-14 per set.

  • Control-oriented players who generate their own power
  • Big hitters who need to keep balls in
  • Players wanting soft poly feel
