2-Tone Backpack Ventilation Frame UL2

It works so well keeping my husbands oxygen concentrator off his back - he could not do the things he does without your ventilation frame and sleeve. He has had to modify it slightly (make it shorter) but it has been a blessing. We are thankful - We hope you are taking the opportunity to sell to folks who have portable oxygen concentrators! we are happy to be testimonials for your company!

Easy addition to my hiking gear.

Helps reduce a sweaty back all year long,even works with child backpack carrier.
