The duro-Med Wheel Chair Back Pack came in real handy when we flew and used a tranport wheel chair for my dad. By rolling each item, I was able to get his airplane blanket, hooded sweatshirt, neck pillow, small waterbottle, and light jacket stuffed into the unassuming black backpack. It suits a minimalist. The velcro was an easy, handy close. When nothing is in it, it folds down to nothing. We were able to hang it on the back of the wheel chair and roll clear up to the airplane door. We used the backpack as one of his carry ons - like a briefcase. It is soft and flexible and can fit into places easily. I'd recommend it. We found it on Amazon.
