Tecnifibre Multi-Feel gives players the best combination of comfortable playability with monofilament like durability. Utilizing a single monofilament core, tension maintenance is increased while an anti abrasion coating known as the SPL technology (Silicium Pyrogene Lubritec) provides added durability. Multi-Feel features 985 multifilament fibers arranged in 6 packets around the monofilament core to give increased power and touch.  Making Tecnifibre strings unique is the PU Inside, a maximum of 20% of a binding agent for the strings, increasing elasticity and providing the ultimate in comfort. For the player seeking multifilament playability and comfort with the added durability of a monofilament core, give Tecnifibre Multi-Feel a try.  Designed to play slightly stiffer than Tecnifibre XR3 with a bit less power.
