Designed to accurately simulate the weight, bounce, slide, and contact height of the ice hockey pucks you're familiar with. Great for street, roller, recreational hockey, or off-ice training, these pucks feature a non-marking rubber with plastic gliding surface that mimics how a puck glides on a fresh sheet of ice. PERFORMANCE TECHNOLOGIES: Same size and weight as a regulation ice hockey puck. Great for street, roller, recreational hockey, and off-ice training. Non-marking rubber with plastic gliding surface to minimize friction. ADDITIONAL SPECS: Intended for shooting and stick-handling practice.
