The BlueStar A2 and A3 offer professional players a softer alternative to the BlueStar A1, which has a 52.5° sponge. The A2 features a 50° sponge, while the A3 has a 47.5° sponge, catering to those who prefer a bit more give. Both models use the Optimised Energy Sponge (OPTE) technology, known for its exceptional elasticity and shock absorption, enhancing overall performance. The development, production, and processing of the BlueStar rubbers adhere to the highest standards, making them a top choice for serious players. These new variants, with their slightly softer sponges, are particularly suitable for advanced and professional players seeking a balance of speed, control, and comfort.
