Game changer in my portable oxygen hassles.
I’ve used many different portable oxygen systems (liquid, portable concentrators, and canned) along with all the different bags to carry them. I’ve used sling bags, backpacks, hip bags, and of course the one they give you.  Perfect bag for my oxygen canisters. Multiple grommeted access points for cannula to exit bag.  Lots of room for wallet and phone.  You can even put in multiple canisters to be on the go longer. Only one thing I’d change is to add (I added small bungee to fix my issue) a second strap lower in bag to keep tank from shifting.
