Large bag, slightly smaller than the Moby XL model.
It is made from a new, light but strong 300-400 denier fabric. The main compartment opens vertically on three sides, for easy access. It has two large zip-up gusset pockets on the front, two side fin pockets, a small pocket on the top to hold the address label.
It comes with a strong fully retractable pull handle that recesses into the bag. The wheels are large and protected. It has two carry handles: a reinforced one on the top and one with Velcro closing grip on the bottom. Stiffening rods have been placed in the back of the bag to keep Moby 4 vertical.
