Backpack Storage & Pockets for added accessories
The G5 backpack features mesh side pockets that are easily accessible without having to move your concentrator. Store a water bottle, extra battery, etc.  zipper pockets and panels for storing backup cannulas and paperwork; The adjustable shoulder straps include an integrated zipper channel that can be used to secure oxygen tubing and cannulas out of sight rather than letting them dangle, and tangle, as you move through your day. Finally, on one side of the backpack there is a special pouch to hold an external battery while it is plugged into (and even powering) the oxygen concentrator!
