Wilson NXT Power 18 Tennis String

Wilson NXT Power 18 Tennis String is my personal go-to when comfort and power matter most. Crafted with high crystallinity Xycro microfibers bonded by flexible polyurethane, this premium string delivers an incredibly soft, arm-friendly feel with explosive pop on every shot. Rated #1 for comfort by the USRSA, it boasts a generous sweet spot and impressively dampens vibration, making every swing feel buttery smooth. Its unique ribbon-like co-polymer core enhances tensile strength and holds tension beautifully, so your game stays consistent set after set. The 18 gauge (1.21 mm) is the thinnest option in the NXT Power line — perfect if you crave maximum power and touch. Once you try it, you’ll understand why it’s a personal favorite.
