The response ball is the perfect goalkeeper training ball for ‘keepers at any level. The reaction ball has its own innovatively designed weight system to give unpredictable and irregular movements when in the air and on the surface. This is to keep goalkeepers on their toes to help improve their concentration, reactions and reflexes. These traits combined are what makes a good goalkeeper and help to improve their shot stopping from range and in one-on-one situations. Manufactured from polyurethane (PU) based material on microfibre backing for a high level of performance. Fitted with a double sheeted bladder and interchangeable valve system, giving the ball excellent air retention and longevity. A great addition to any group or individual goalkeeper training session.
