O2TOTES USA Backpack Custom Fit Inogen One G3/Lightweight/Fits The Inogen One G3 Unit + Accessories/Designed in USA

Great fit and nicely made . . .

Deivered on time and Product was exactly what I was looking for.

This is my second carry oxygen for my G3 and I have loved my first identical one except for a color change. The carry all worked as promised and still has usage left. No reason to not get the new one. One improvement from my old one is there are two grommets for feeding your oxygen tube. Only one and too small on the first one so great design change. I hope design changes continue with how easily the o2 tube can kink but it all still works with some paying attention to not interrupt flow! Best on market in my opinion!!!

The backpack has afforded me an opportunity to be 'hands-free' when I'm out and about. It is very easy to use and comfortable. The shoulder straps are adjustable so that I can wear it with or without a coat. There is a cross-body strap that is also adjustable (it can also be used across the shoulders or lower on the body to help stabilize the shoulder straps and keep them from falling off). The quality of the product is commendable. The carrying handle is also a nice option.A couple of suggestions for the design - more color options, waterproof, slightly larger pockets, a flap that covers the entire top of the InogenOne G3, and possibly a waist belt/strap with padding to help keep it in place when bending over so the machine doesn't hit the person in the head :) I guess it is just a reminder to "bend from the knees" :)Once you have taken off the backpack and intend to use the carrying handle, be sure to grab all of the straps because they tend to dangle and can cause one to stumble (not that I've ever done that! :)Overall, I'm glad I purchased this backpack and am thankful that it is available.

These bags are not as described or pictured. There is no silver ring for the cannabis to go through. My line bend and prevent air flow.

I bought one of these about 4-5 years ago, and wore it out. This new back pack has an additional strap along the waist area. This helps make my portable concentrator more stable especially when I am planting flowers on my hands and knees. With just the chest strap there was a tendency to sway side to side when walking or bending etc.This backpack has plenty of ventilation for the concentrator to keep cool. The storage pockets/ pouches are very convenient for an extra battery or other items you may need to carry with you.

It is hard to wear something like this for a long period and be comfortable. That said, I found it to be more comfortable than I thought it would be. I wear it everyday for at least 1 to 3 hours. Readjusting it from time to time helps. It has given me a mobility I had lost. On durability, the top end of the back straps are tearing off and the base that the battery sits on, has a stiff plastic item in it. That piece is tearing the base material. I fixed the back straps with a very heavy thread I use for sawing leather. Now it's just fine. Maybe a little heavier material at weak points would solve these problems. I can't do without mine.

When I recieved my order, I quicklyrealized I had ordered the wrong bag as the vent openings in the bag didn't line up with my machine. I went back to Amazon only to learn my item wasn't returnable using that process. Disappointing because Amazon process is so easy. I contacted the seller directly ansd was most pleased withir customer service in making the exchange so easy/Love the correct bag, It is an easy to use back pack that gives some room for storage and leaves my hands free. My onle complaint is that recharging while in the backpack takes some effort to ge the plug right.
