Frees a person on oxygen to use both hands
This backpack has been extremely handy for me as I am able to go about my daily outdoor chores using both hands.  The shoulder straps are very comfortable and the pocket for carrying an extra battery for my Inogen One G4 portable oxygen machine allows me to be outside longer.  I highly recommend this to anyone that has a portable oxygen machine. The price is very affordable.<br /><br />Ervin Harmon
