Fatboy Lamzac 2.0 is an inflatable bean bag chair that you can take with you wherever you want. Lamzac is not filled with a pump, but is filled with air from the open side, the mouth opening is rolled up and closed with a clip. The chair is emptied after use by rolling it up and closing it back into the included carrier. The water-repellent nylon ripstop fabric allows Lamzac to be used on a wide variety of surfaces.
