CURMIOTravel Backpack Compatible with Inogen, OxyGo and Caire Units, Portable Oxygen Concentrator Bag with Storage Compartment, Black (Bag Only, Patent Pending)

I was really on thd fence so I decided to go with the inexpensive model knowing I could return it. It is PERFECT. Machine fits well and securely, vents properly, is just a little awkard to plug in charger, and is just the right size for my other belongings. I did find putting the cannula through the side as suggested cause it to crimp, so I just ran it straight up instead. Works perfectly. Save yourself some money and order this one.

my machine doesn't get hot in this bag like it did in my first one and lots of room to carry my charger and extra battery

I have had this unit for almost a year and I am very happy with. It can carry a lot of "stuff", spare batteries, chargers, laptop, small blanket, etc. There is a small zipped pocket that can hold your wallet and keys. Yes it can get heavy only because you stuffed to much stuff into it. If you want a streamlined bag there out there but if you are traveling this will to the trick. The only down side is it can run hot. They way around it is to not zip the concentrator to tight and to make sure when you store it under your set when traveling so that it can ventilate.

This backpack has side flaps for threading the tubing through, so no cinked tubing. Lots of useful space and a stylish look. Your concentrator is safely enclosed and space for a water bottle or two is there as well. No need to carry an extra bag for your wallet or phone anymore.

Didn't fit his but returned and no problem with getting money back

This is a very nice bag, but was too big for our concentrator and was awkward for my husband to wear. Of course he's not a back pack type of guy, but it does wrinkle up your shirts and it takes some getting use to. I think the little carry bags that you get with the concentrators work fine, at least for our needs. We thought this would be easier to carry the device, but it's too cumbersome. Maybe it doesn't need the extra backpack part and just the device carry part.

My Precision Medical Easy Pulse 5 fits great. Makes it alot easier to carry on my back vice one shoulder. Seems durable and well made.

the back pack fits my inogen g5 very well and is easy to use with plenty of extra room in it for thing that one needs to carry along with them only complain i have at all is if you run your oxgen machine for longer periods of time as needed you would need to take it out of the back pack i think the clear plastic or viny cover that goes over the top of the machine keeps to much heat inside when the machine runs for longer periods of time might work better with some kind of mesh instead of plastic so the machine could breath more easily when running
