This Skate Bag is both a Rolling Trolley Bag and a BackPack (where the Straps can hide away) The EDEA Trolley Jacquard is made in sturdy polyester. The bag is durable, strong, and washable and makes carrying skating equipment even easier. The Aluminum Extension Handle extends to normal walking height when used as a Trolley. In the Back Pack configuration, the Adjustable Padded Shoulder Straps come back out of the pouch and snap onto the Bag and allow great comfort against the back with the Anatomically Padded Airtech Mesh Inserts to provide outstanding ventilation, protection, and maximum comfort. The Urethane Wheels with Precision Bearings are 80 mm with a reinforced hub, making them silent and durable. We’ve added a Nylon flap to cover the wheels when using the trolley as a backpack. The EDEA Trolley Jacquard will fit in most Airplane Overhead compartments and is: 45cm x 39cm x 26.5cm
