This bags number one feature is our patent-pending Big Mouth Opening. We have placed a heavy-duty plastic extruded ring into the mouth of this rugged bag to hold it open for no hassle super fast loading. Next, we styled the cut of this bag like a Pyramid, wider at the bottom and narrowing to the width of our Big Mouth Opening. This allows this bag to stand up without tipping over like most other decoy bags, except of course, Drake's very own Patented Stand-Up Decoy Bag. Last of all, this bag is built to last for years and years of rugged abuse. We use rugged vinyl coated polyester for our material and we top this bag off with easy to work with polyester mesh for the top closure. Once again, not a detail was overlooked in this design.
