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.
