Same Great Backpack! Just for a little less! (REFURBISHED ITEMS ARE NONREFUNDABLE! EXCHANGES ONLY) The universal mesh backpack is a highly breathable ventilated and adjustable length backpack designed to hold various oxygen concentrators. This backpack features our signature ventilation system with mesh distributed throughout the backpack, front, back, sides. Our mesh ventilation system is designed to keep you & your oxygen concentrator cool. Why is this important? Did you know that your oxygen concentrator is 10x more likely to break if placed in a backpack or carry bag without the proper ventilation? We take the steps necessary to ensure proper safety of your unit, whether it be this backpack or any of our other backpacks. All of our carry bags & backpacks are tested with real units, real people. Safety is always #1   These backpacks are renewed meaning they are returns that have been sent back for reasons such as: Bought for the wrong unit, bought a different backpack, wanted a carry bag. Backpacks are in excellent condition in new packaging. Everything is exactly the same. You may receive a backpack with or without the grommets. The grommets are actually discontinued do to the lack of keeping the cannulas non crimped.  We have 2 different sizes of this backpack, choose which unit you have for the correct size when ordering.
