Manufacturers of skydiving canopies. A "canopy" is the technical term for a parachute. The "container", which is worn like a backpack and holds the canopies, is not part of the canopy, and is often purchased separately. Most containers intended for sports parachuting hold two canopies, a main and a reserve. This means that if there is a problem with the main canopy, you can cut it away and open the reserve. (Note that "Skydiving" and "Parachuting" mean the same thing).
