BAGSFY Portable Oxygen Concentrators Backpack Compatible with Inogen One G3 & G5, Lightweight Oxygen Machine Carrying Bag (Gray)

If you know what the case is for then you know how hard it is to get case for it... This case is small with the storage space at the bottom ...I don't like this makes hard to get it to stand up on its own. As for small I am a man with borad shoulders and its really hard to put on, even harder still to get on ... WAY OVER PRICED!!!!!! the construction is sturdy and the unit fits the well, just some one should have thought have thougt about the wearer. I don't like it!

To have an air machine suitable for this, maybe! But I would strongly suggest you consider if a backpack is worth, a view or could you get something similar from Amazon, I would strongly recommend their products I have purchased many over the years. So I would suggest you try to get something a little cheaper. No back pack is worth $86

For my G5 concentrator with the big battery this is an optimal back pack with pockets on the sides and a zippered pocket on the bottom, with lots of room for a second big battery and other items

This little bag has given my wife so much mobility! It's sturdy and convenient. Much better than the standard shoulder strap the O2 machine folks issue as a "standard".

Updated: The seller contacted me right away after my review and customized me a whole new backpack for my inogen g3 to fit properly. I’ve been using it alot for travel and it’s been holding up extremely well. I’m glad the canula doesn’t fold like it used to and it fits perfectly! Thank you so much for caring for your customers and the quality of your product Old: Too snug for the inogen g3 with double battery. It squeezes the Canula hole making it hard for the oxygen to flow when using it. It’s comfortable on the shoulders but I wish it fit and the holes were in the correct spot. Have to unzip it to charge my poc. Overall I travel often so I guess I have to work with its flaws
