Portable Oxygen Tank Backpack Holder for Size D (M-15), Comfortable Medical Oxygen Cylinder Backpack Bag with Durable Straps, Size JD (M-22) Oxygen Bag for Travel - Easy to Carry (Black)

I bought this for my wife. She loves it. A good product!

Huge difference from having bag that oxygen company supplies. My oxygen cylinder weighs just under 12 pounds and being able to carry it on my back opposed to strap over my chest and tank to my side is huge. I just got it 3 days ago and will have to figure out which of the holes for tubing works better but that's a good thing because there's 6 I believe compared to 1 for company bag.

Super helpful. I had a side bag, and it hurt my neck to carry. But, this bag is well made and comfortable. It balances the weight better than a side bag. It's light but sturdy. Pockets hold a cell phone and one for keys or a wallet. I use it for a C size tank, but a D tank would easily fit.

My wife has the 30” oxygen bottle and it does fit it the back pack height wise but it is a pretty tight fit.

Seems like it will last for awhile. Just received it, so only time will tell.
