O2TOTES Backpack for Inogen One G3 & Standard OxyGo – Lightweight, Vented, Zippered Bottom, (Does NOT Fit OxyGo Fit or Next)

I considered several backpacks before selecting this one. I read a several reviews of them all before deciding. After a month of daily use, I am sharing my experience. First, my Inogen One G3 fits perfectly in this back pack. Also, I have experienced no issues regarding the quality. The cannula and charging ports are easily accessible. I have absolutely no complaints.

This is a backpack specific for my Imogen G3. I’ve had it a month, and it has been excellent. It has more room than absolutely needed, and it doesn’t fit like a glove, leaving room to carry several small items: charger, batteries, spare cannulas, wallet, keys, etc. I use it to hike in parks and at the seashore, and I carry it around the house too. There is an opening for a charge cord to connect that aligns correctly when the pack it shifted correctly. It has proven to be tough and durable and well suited for its purpose.

Great product! Bought strap extenders as usually back packs are usually too snug on him but didn’t need them. Nicely designed

this back pack does Not Fit my Concentrator Exactly, it's more of a Generic Fit. But it Does Hold the G3 inside it and has been very Functional since I have had it. I wear it most every day. It IS Worth the Money

Great fit and nicely made . . .

This backpack fit my Inogen G3 perfect and the shoulder strap’s padding is very comfortable. I can now do my chores and property tasks without having the G3 sliding around or getting in the way. It could come with a Velcro strap to hold excess air tubing and also a small clear plastic pocket for ownership info. (I put a luggage tag on mine in case I accidentally leave it somewhere and made a Velcro strap to hold the excess air tubing.).

It works to hold the concentrator, but it doesn’t fit snug in the backpack like it does with the carry bag that came with the concentrator from Inogen. This makes it annoying when trying to change settings, I have to open the top flap, I can’t just do it through the clear plastic window. The straps aren’t very comfortable. It looks like it is sturdy enough. Hopefully it will last.

I bought one of these about 4-5 years ago, and wore it out. This new back pack has an additional strap along the waist area. This helps make my portable concentrator more stable especially when I am planting flowers on my hands and knees. With just the chest strap there was a tendency to sway side to side when walking or bending etc. This backpack has plenty of ventilation for the concentrator to keep cool. The storage pockets/ pouches are very convenient for an extra battery or other items you may need to carry with you.
