OxyComfort Bag and Strap Systems
are available for all three common medical oxygen tank or cylinder sizes
in use today, the "B" (M-6), "C" (M-9), and "D" sizes.  Each system consists of the unique OxyComfort Strap and a matching bag made of closed cell neoprene that is soft and comfortable but yet strong and durable.  The bag features a screen mesh window for oxygen venting and easy viewing of the regulator gauge dial.  Entry into the bag is made by opening the dual zippers that surround the mesh window's periphery. The opening between the zippers also provides for a convenient cannula tubing exit as they can be positioned at any point around the mesh window.
