The Bosbag has been around a long time with a lot of knock-offs. This is the orginal. It's practically indestructible, stands open for easy loading and then folds down flat for easy storage. It is made from a heavy duty, tightly woven polyethylene. Mine is going on its ninth year. It's the first thing I grab when I go outside to "hunt and gather" for weeds and spent flowers. It's also great for college kids who bring home their laundry although you might not want to encourage that. It only weighs 10 ounces and has a 3.25cubic foot capacity. For yard clean-up you can't beat Lawn Claws and a good carrier.
