Yonex Exbolt 65 is a thin-gauge badminton string at 0.65mm, engineered to deliver a sharp, responsive feel and extra spin on the shuttle. Thinner strings like this bite deeper into the shuttle on contact, which helps with spin serves and net shots, but they generally wear faster than thicker gauges under repeated hard hitting. Exbolt strings use Yonex's shock-absorbing technology to help offset that tradeoff, aiming to keep tension and feel more consistent over the string's life than a typical thin string. It's a good fit for advanced players who restring regularly and want maximum feel. Each reel is a 10m set, enough for one full stringing job, available in multiple colors.
