O2TOTES Backpack For Inogen G4, Ultra Lightweight backpack|/Backpack Only, Does not come with O2/Only fit for the Inogen One G4

I have an Inogen G4 and this bag is the perfect backpack for it. Zips along the bottom which allows me to change batteries without removing the entire unit. The top also opens, allowing direct access to the top of the unit. The aluminum nozzle is not obstructed by the case. Additional holes in the back of the bag are metal grommet reinforced so the bag will last a long time and it can be washed without fraying.

I was looking for an alternative to the Inogen provided cross-body bag which only has one shoulder strap. I thought this would be more comfortable but it is not. It's very awkward for me to get it on properly .. I am a small woman and trying to cinch the straps tightly enough without making the arm holes too small was just a real pain. I can't imagine trying to quickly put this on when getting off a plane! Also, 2 complaints. The nasal tubing must be passed through the grommet in the top flap...That is a nuisance! The top flap should be configured to go around the tubing so you can change it quickly if needed. Also, there are no hooks to hang anything such as the cannula holder which I bought to keep the cannula off the floor. There should be some loops or hooks provided . I am staying with the Inogen bag. It is much more sturdily constructed and much more comfortable for me.

Backpack would have worked fine no problem with backpack just wrong color

Works very well with my inogen machine. Very durable

The holes for the charger cord or only on one side of the backpack, not both sides. Also, the waist level cinch is not removable. IDK if the product picture shows a waist cinch or not.
