With a single swing, you can fill the bag with air in seconds. You close one of the chambers, then with a second swing, that chamber is also filled with air. Twist and seal, and the Lamzac Hangout is ready for use. When it's time to go home, simply release the air, fold it up, and store it in the included transport bag. The Lamzac Hangout is made from very lightweight yet highly durable nylon fabric. Indestructible and robust, it can be used over and over again. The maximum allowable weight is 200 kg.
