You are buying a brand new Sill Sack for your helicopter (or airplane) door.
Avoid FOD and loose items getting lost in the aircraft and tangled up in the flight controls. The traditional door nets are great for holding pubs, but not small items like pens, flashlights, rags, tools, etc. Contain all your small items in a sack that has a zipper.
See pictures (shown in the pictures is the sill sack in a Bell 407). Contains your items and looks nice too! And easy to access in flight and easy to carry in and out of the aircraft.
Made from durable canvas type material, padded, with a zipper to keep items contained. Also has a Velcro strip on back.
