Wonderful fit. I'm super excited to replace this beautiful backpack instead of my old black worn bag. !!!

This bag didn’t meant to be carrying a e tank oxygen it’s way too small. Trying to see if I get a refund

The holes to put the cannula through are too small. You have to feed the cannula from the inside to using the hose piece and squeeze it through the hole. It's very inconvenient to do this. Also, I'm a little disappointed there is only one pocket, I thought it would have two. The description might have said it only had one, I just don't remember

I have had my Vive Cylinder Backpack for almost three years and I love it! It easily fits a B or C tank with room for my phone and keys in the outside pocket. I like to sling one strap over my shoulder when out shopping (then I sit it in the shopping cart) and I wear it as a backpack when gardening or talking a walk. The only issue I've had is one of the black lower grommets (that I use the most for my tubing) falls off now and then, but it easily snaps back together (until the next time it falls off). The outer grommet doesn't get lost because it stays connected to the tubing running through it and the inner grommet falls to the bottom of the bag. The bag will stand up on a flat surface as long as there is a tank inside it. The two zippers on top makes it easy to open the top fully to replace the tank and to open the top just a little way to easily change the setting on my tank. I've had nurses at my pulmonologist's office mistake this bag for a purse! It's got a little wear on a bottom corner after three years of use but it's easy to clean (just wipe off) and very durable. I have this in the gray.
