The custom carrying case is the most efficient way to protect the Respironics SimplyGo portable oxygen concentrator from everyday drops, bumps, and scratches. The carrying case is specially fitted to the exact dimensions and airflow needs of strictly the SimplyGo. Not only will it protect the unit, but it also delivers two carrying methods—an adjustable shoulder strap and handle strap—so you can choose which way is most comfortable for you. If you ever need to access the control panel on the Respironics SimplyGo, you will not have to go through the hassle of removing the carrying case just to adjust a setting. The control panel can quickly and easily be used at any time whenever the SimplyGo is in the carrying case. Keep items such as your oxygen prescription or other small personal items in the front zipper pocket of the custom carrying case—the perfect pocket to keep your ID, oxygen prescription, and flight information whenever you are traveling so they will be in one convenient location.
