While I think the blue KobraJet hose that we sell is better, this gray hose is the next best thing. Some people may prefer the gray hose so that it fits their color scheme better. I am offering this so that you can make that choice.

Functionally, this gray hose is identical to the blue one. This just has a rough texture jacket, where the blue one is smooth.
