O2TOTES USA Portable Oxygen Concentrator Mesh Backpack Compatible with Inogen One G3 & Inogen One G5 (Fits: Inogen One G3 & Inogen One G5, OxyGo & OxyGo Next)

I know, it sounds crazy, but I used to love my work, walking around a hardware store telling people how to not mess up their plumbing. This bag let's my Inogen breathe! So it can let me breathe! Also has a lower removable portion, that I took off, but would be perfect for accessories, batteries, etc. I bought 2 foot cannula for it, and it runs right down the right strap, so I don't have coils of extra tubing to tuck away. Highly recommend this bag! Great quality! I'm back to work for the time being, and this bag is a part of it!

I have used tote bags that would slip off my shoulder - or put all the weight on one arm. This backpack is brilliant - freeing up both arms and distributing the weight. Bonus is there's enough room to carry inhalers, a small wallet, and cellphone.

Good quality and has room for keys and wallet, etc. It was too bulky and awkward to wear and my portable felt heavier than it is hanging on my back. I didn't find it comfortable to wear at all

The backpack is well-made. It doesn't quite fit the Inogen 3 so I added new holes for the oxygen tube and charger.I had accidently ordered the wrong one the first time but the vendor accepted the return and sent the right one.

I was pleased when my O2TOTES Mesh Backpack arrived to discover that this lightweight and inexpensive alternative to the other backpacks available for Inogen Oxygen concentrators is the handy item I have been looking for, for years. I have COPD and have needed supplemental oxygen for several years. It was always awkward, using both hands to carry my oxygen and a briefcase to meetings and appointments. Now I can easily put on this lightweight backpack and carry my oxygen with me, as needed. The middle picture shows it with an Inogen One G3, but it also holds the G4 and G5, just as easily. Inside the backpack are two straps to hold the devices in place, and has padded adjustable arms straps and a chest strap, included. As an added bonus there is a zippered compartment at the bottom for storing extra battery, wallet, cell phone and/or charging cables for your devices. It appears durable and should provide me with years of frequent use. If your use oxygen check out this backpage, and save the high cost of the factory model. Be sure to face the air vents on your device to the back mesh closure to allow your device to breath.

worked for a short time, 90 days were up so I couldn't return it, tried to have it repaired locally, and the tech refused to work on the brand. Reached out to the company to direct me to someone in the USA who would repair it , ask if they would send me the schematics and never heard back from them.

My Caire Freestyle Comfort fits with room to spare with an 8 cell battery attached. I especially like the large bottom pocket which is big enough to store an extra battery and the chargers. The straps are nice and thick and very comfortable. I did not like the side carry bag the machine came with, it swings around any time you bend over. I will enjoy using this! I do a lot of hiking.

I’ve carried a portable oxygen concentrator for 2 plus years now. This backpack is a wonderful investment. I feel more comfortable carrying my machine now because it’s not digging in my shoulder. It’s weight is evenly distributed across my back and shoulders. Although I have a small unit, it becomes cumbersome hanging on my shoulder after a while. I stayed home a lot because of the inconvenience of having to carry this thing that kept falling off my shoulder.Since purchasing this item, I have now regained some of my freedom to move around unencumbered. I used to carry the bag with the machine and another with the extra battery and charge cord (just in case). Now everything fits into this one bag.Thanks so much Amazon.
