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 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.

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!

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

Works well with my Inogen One G3 with either small or large battery. Interior straps hold it securely. Extra room inside and bottom compartment easily holds both charging cords and extra battery. Grommet configuration works well. Not a custom fit, but for the price works well. Was not sure from pictures and descriptions, but mine came wit a chest strap and waist belt.

Bought and returned different ones and some say for the "Inogen 3" and the expensive unit flopped all around, got too warm or the hose crimped. All outlets lined up with the unit. Strong and durable to carry my "freedom from home" machine.! Plenty of room for cords, tubing, wallet, keys, cell phone, tissues, bottle water and then some. Light to carry as well. Well worth every penny spent and I think can be used for the next machine up should I need a bigger unit. For something so life changing as getting your freedom to move about in public with hands free, & to know of bumped it will not rip or tear or come loose.

I removed the bottom pocket to help the pack fit better. Armhole straps large enough for XXL (or more.) Needed to cut mesh for charging outlet but the mesh has not unraveled around the cut. Ive used it for several weeks now for gym exercising, grocery shopping and moving around my back yard. It's very satisfactory.

As it is an universal backpack, it is designed to fit many concentrators. It is way too big for the G3. Otherwise liked it and felt it was an excellent value.

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.
