OBO's ROBO left hand blocker is built smaller for increased stability and better ball control. This Hi-rebound hand blocker is shaped to control the ball and direct it downwards. The elastic strap on wrist helps keep the hand protector secure at all times but does not inhibit movement.ROBO equipment is specifically designed for the elite level goalie. This is the hand protector most Olympians rely on for performance, style, protection and complete confidence. OBO foam is specially designed with a much tighter cell structure than foam from other companies. For goalies, tighter cells mean that OBO foam lasts much longer and maintains a consistently high level of rebound over time.
