NRG2 in short

Tecnifibre NRG2 features 1,120 individual Elastyl fibers bonded with polyurethane resin offering 400% elasticity. This gives 12% more power than standard synthetic polyamide strings.

"Let's not mince words, Tecnifibre NRG2 is powerful" - ideal for players with slow to medium strokes still developing their swings. Playtesters raved about the soft, buttery feel. One of the best tennis strings for tennis elbow.

Wilson has packed it with even more shock absorbing fibers than the original NXT, delivering outstanding comfort and feel. Makes modern stiff frames feel perfectly dampened. The closest synthetic alternative to natural gut in terms of pure comfort.
