A four wall flat bottom bag made with an additional gusset at each corner that extends outside the walls of the bag, making the bag much easier to grip and carry when filled by gripping the outward facing corner gussets as handles. The outward facing gussets make the bag easier to open, by gripping the gussets to pull the bag open when tall bags cannot be reached from the inside bottom to push open. The outward facing gussets help to keep the bag open by providing additional expansion and support at the corners. The outward facing gussets give the bag more stability, making it less likely to tip over when filled. The gussets make the bag less likely to tear at the mouth when being filled by creating a larger opening, making the bag much easier to fill and increasing its capacity.
