What is PVC gauge? What is nylon cover strength?
RANDY E not sure about the gauge or the strength, but if you an average size adult this tube is not comfortable, I gave these tubes to my kids and bought different ones for me an my wife. I don't recommend these tubes!
Brett H The mfg has not provided a PVC thickness or nylon strength on this product or any of their similar products. Overall Sportstuff makes excellent floats and towables that should last quite a while, and this being one of the covered models it's about as tough as they get.
