iGuerburn Oxygen Tank Backpack Size D, Portable Oxygen Backpack for D/M15 JD/M22 Cylinder Bag O2 Tank Carrier Holder for Travel (Black)

Plenty of straps secure tank inside backpack and good chest strap with flexible fabric connects shoulder straps so straps stay not slide down stay in place and snug without being to restrictive. Good value good quality.

Seems well made, sturdy, comfortable. Will see how the zipper holds up which has failed on other cases (not this brand)

I did not buy this backpack for medical oxygen tanks. Instead I’m using it for two 2 liter 4500 psi PCP refill tanks. They measure 20.5” height with valve and 3.5” diameter each. Perfect fit and function for my purposes. Could not find anything close to this useful size pack for my 2 liter tanks when carrying in the field. Very comfortable and protects tanks.

I really like this pack. Towing a cart or carrying a tank over 1 shoulder or around my neck is VERY uncomfortable. Great for shopping, walking, etc. Two hands free makes a BIG difference !So far, (about 2 mos.) I have seen no evidence of ripping/tearing straps. Of course, I'm careful putting on and taking off after reading some of these reviews. I am 6'3" and have no problem w/strap size or length, but I agree straps would benefit from a stop at the ends. Chest strap is fine.Could use stronger bottom, perhaps molded styrofoam insert to help with strength and stability. I always lean it against something, as it will tip over if bumped, but stands ok if out of the way.They say 6 grommets, but 2 are in face layer of lower pocket (see pict 1) and don't go through; thus, they are useless, but don't really need them.I curl hose/cannula and put in pocket, along with wrench (pict 2); wrench tether goes thru grommet with hose and attaches to regulator screw. I agree that the lower set of tank straps are difficult to access, but it's gotten easier to use them with practice.All in all, very satisfied with this purchase and recommend this product.

There's nothing like an oxygen backpack and this one fills my needs. The tank is rather heavy but will last me for just about 8 hours. Its a D tank. Just fits in there neatly. I've come to love these types of back packs because they really in my case gave me back my freedom. I have both hands free to do what I want with. No more pushlng that metal cart around in front of me. Quite frankly I feel like a human again. So far I've bought 3 backpacks. 2 for C tanks. 1 for D tank. The only problem I had was the first C tank carriers zipper came apart at the top of the case. I couldn't fix it. So I reported it to Amazon. They gave me an email address to send my complaint to. Unfortunately I never got a call from them as they stated in their email msg. So Amazon gave me a gift card credit towards my next purchase. I later received an email msg stating I was going to get a refund for the carrier since it was still under its year warranty by the manufacturer.As they say or I say all that starts out bad doesn't necessarily end up bad.

This bag is so much better than the one I was given by my oxygen supplier. Shoulder straps are nicely padded, and carry handle is easy to use as well. Plus it looks nice. Deeper pockets on the front would be nice, but overall, it's a great bag.

Works perfect for walking or scooter. Bought 1 3 years ago

The backpack is a very tight fit for a D size oxygen tank with a regulator attached. It could use an additional inch of interior length. Also, the side zippered pockets could be a bit roomier. There is not much room in them for anything useful.
