Not sure if this has been shared before for 88 cu ft air tank storage. I needed something for another tank I recently got, so I took a chance on this bag from https://www.emergencysafetysupply.com/kemp-usa-premium-oxygen-cylinder-bag/, works great, keeps valve protected for transport and end has zipper that goes to bottom so you can access the valve while you’re at the bench. Plenty of storage for accessories and stuff, nice padding all around, carry handle, shoulder strap, nice zippers, seems nice and sturdy. Dog and air tank are not included.
