iGuerburn Small Oxygen Tank Backpack for Size M2, A/M4, ML6, B/M6, M7, C/M9, Portable Oxygen Backpack Cylinder Bag O2 Tank Carrier Holder for Travel (Not for Size D Tanks) - Red

I looked for awhile before settling on this backpack and I have to say I chose well. Its got a nice shape, fits well in the small of my wife's back and is a slim design. Red colour is a nice touch. I was worried it wouldn't ventilate enough but it is has several holes that work well for that. It's got a velcro strap that wraps around the tank and secures it. A plastic bottom provides support for the tank and the bottom of the pack has four plastic "nibs" as feet to allow it to stand up, although that depends really on how well you balance the tankWe've had it for months and it performs perfectly. Highly recommend.

This is great for an oxygen bottle. The only problem I found is the single bottle strap will not hold the bottle in place. II inserted a strip on foam rubber on each site of the bottle and it holes it in place without any movement.

The bag itself is great however, they use cheap plastic clips that have already broken.

This bag makes carrying your oxygen around a whole lot easier & leaves your hands free, I can go on walks now with my dog

I find this backpack style tank carrier way better than the over-the-shoulder style.Will see what it is like in the winter...Roomy enough to carry hoses,key,etc.Good product and I believe it will last a good while.
