The Bauer core player wheel bag is designed with Bauers innovative features, and with knowing how tough hockey players and their equipment are on their bags. The core wheeled bag is designed with strong and durable polyester fabric and heavy duty PVC fabric backing. The core bag features a large U shaped top opening with double zippers so your stuff is easy to find when getting ready and hard to miss when packing up. The outside of the bag has plastic bumpers to reinforce high friction zones, and the straps and grab handle have durable reinforced webbing. The wheeled bag features a durable internally constructed handle, inline wheels, and sturdy plastics rails that provide stability and raise the bag off the ground. Also all components are cold resistance tested to prevent cracking. Lastly, there are strategically placed ventilation holes to help relieve some of that hockey smell we all dread!
