The Pro backpack from Powerslide is super stable and light. Made with reinforced compartments so that inline skates and roller skates can be stored securely on the front of the backpack. The inner compartment is large with smaller pockets for small items. The anatomically formed back panel with extra ventilation channels and comfortable load bearing shoulder straps means this backpack is super comfortable to wear.
Pick one up at the World Of Wheelcraft skate shop in Sydney.
