## Description

Since 2007, O2TOTES has been designing & manufacturing portable oxygen bags & backpacks for oxygen companies across the world. A small, family-owned company owned and operated in the heart of the U.S. Designing oxygen bags is what we do. We utilize safe materials, innovative designs & create products for individuals who want & need a better option. We never use our logo on our backpacks or carry bags, we want your bag or backpack to be less medical and more you.

Review: Just took delivery on this little O2 concentrator backpack. I am of average height (5'5") but am very, very thin (under 100 lbs). I was worried that I would have to draw the straps in so far to make the backpack fit me that I would have miles and miles of 'extra' strap hanging everywhere. I am very happy to say that there is plenty of strap length so the pack straps can lengthen to fit over bulky clothing/coats but not so much strap that I'm drowning in/tripping over excess strap length when wearing the pack over regular clothing. If you are a larger person, I'm honestly not sure this pack will work for you if need to wear it over bulky clothing. The pack appears very sturdy, and is well sewn. Fits my Inogen G3 perfectly...like a glove (it WILL NOT hold a larger machine). Has a neat little zipper flap thing on the right shoulder strap to help contain/guide your oxygen tubing. It's not terribly obvious in the photos or mentioned in the product description, but this pack DOES have a waist strap (the text on the product photos mentions it). The padding on the shoulder straps is nice and wide. The color of the pack is not a vibrant pink; up close, the fabric actually shows a variegated blend of colors in the weave that from a distance overall reads more towards a light burgundy. It's a lovely color. The pack accommodates an extended battery with ease, and a pad is included to fill the space left over if using a "regular" battery. So far, I am very pleased with this purchase, especially when you see other, supposedly "fancier" packs that are far more expensive with poor ratings. This is a great little pack!
