Tecnifibre NRG2 is one of the most established and respected multifilaments in tennis — effectively the “OG” premium multi. Built using PU (polyurethane) bonding and thousands of microfibres, it was engineered to replicate the feel and power of natural gut at a more accessible price point.
Having tested it across multiple frames, NRG2 stands out for players who want effortless power, plush comfort, and excellent touch. It’s no surprise it remains a favourite among players with arm issues, doubles specialists, and anyone seeking maximum comfort without sacrificing control.
Quick verdict
Tecnifibre NRG2 remains one of the best all-round multifilaments ever made. It delivers elite power, superb comfort, and class-leading feel, while offering better stability and tension retention than most multis. Spin is modest and control can drop on very fast strokes, so big hitters may prefer something firmer or hybrid setups.
👉 Perfect for players needing comfort, free power, or gut-like feel — especially those dealing with arm issues or who prefer a softer response.

How it plays (feel, spin, power, control)
From the first strike, NRG2 feels plush, lively, and incredibly easy on the arm. The polyurethane binding produces a soft, buttery pocketing effect, giving the ball a cushioned dwell time you feel immediately. Touch shots — drop volleys, touch passes, half-volleys — feel almost gut-like.
Spin generation is moderate, as expected from a smooth multifilament, but the string rewards clean technique with a predictable trajectory. Power sits right at the top of the chart: depth is effortless, and even compact strokes produce penetrating ball speed.
Control is good at medium swing speeds thanks to its consistent response, but advanced players with long, fast strokes will find it launches too high unless paired with higher tensions or a poly hybrid.
Durability & tension maintenance
Multis typically struggle with durability — but NRG2 performs better than most.
- Tension holding: 100% (best-in-class for multis)
- Stability: 85% — retains feel across multiple sessions
- Fraying begins after several hours
- Notching happens gradually but doesn’t immediately affect playability
For non-string breakers, it lasts a respectable amount of time. For heavy hitters or frequent topspin players, a hybrid with poly mains can extend longevity. See my guide here on choosing the right tennis string tension.
👉 Overall: one of the longest-lasting and most stable multis on the market.

Comparable strings
If you like Tecnifibre NRG2, consider:
- Wilson NXT – softer, slightly less crisp
- Babolat Xcel – plush comfort, less power
- Head Velocity MLT – cheaper, firmer, good all-rounder
- Tecnifibre Multifeel – more control, less power
Practible recommendations
Tension: 24–26 kg for most players; drop to 23 kg if you want extra comfort
Gauge: Choose 1.30 mm for maximum durability; 1.25 mm for more feel and power
