Players who snap strings frequently prefer polyester strings for their robust durability. However, due the hard feel of conventional polyester strings, there are a number of players who experience stress and fatigue on their arm when hitting the ball. The new POLYTOUR AIR solves this problem by offering players an arm-friendly string with a super plush feeling. POLYTOUR AIR features the all-new “HR-Elastomer” material, which retains the strong repulsion power and durability of traditional poly strings while reducing stress on players with a light, soft feeling upon impact.
The POLYTOUR AIR is the perfect string for players who desire easy access to power with minimized shock.
We tested the softness of the new HR-Elastomer material in the POLYTOUR AIR against a conventional polyester string by bending one of each. While the conventional polyester remained bent, HR-Elastomer returned to its original state.
Furthermore, as indicated in the graphs below, the POLYTOUR AIR cuts down on shock by 20% and sees flex increased by 1% compared to the conventional model.
