The J2NFK uses a woven Kevlar surface paired with a 16mm variable-density EPP core and a notched EVA foam perimeter (“NF”). Among the NF lineup, this one offers the most plush and connected feel. Kevlar naturally damps vibration and delivers a grippy response, making this paddle ideal for players who value touch, controlled resets, and hand speed—but still want linear, predictable power from a standard hybrid shape.
