This reusable bag on wheels will make schlepping easier! The Hulken is made of polypropylene, polyethylene, and “memory fabric,” which is a combination of several layers that keep the bag standing upright for simple and stress-free packing. The bottom board is extruded from recycled material, and the swivel wheels are made of stainless steel. This bag folds flat for easy storage when not in use and includes an acrylic Cambria tag for an extra pop of flare.
