Right past the core is a .040” Ionomer mantle layer with new formulation that generates even greater ball speeds. Surrounding the Callaway HX Pearl’s mantle is a Pearlized Ionomer cover that has been made softer to offer an enhanced feel, while still outputting greatly increased ball speeds. Lastly, the cover features an aerodynamically-designed HEX with 332 dimples that eliminate seam, enhance shot-to-shot consistency, and reduces drag for long, efficient ball flights with high stability. Callaway HX Pearl golf balls retail for $25.99 per dozen, and come with a 2 year limited warranty that covers defects in materials or workmanship.
