Re: Hookah-Hookah hose not reviewed
They're wider and a bit longer than normal HookaH-HookaH synthetic leather hoses if you have any experience with those.
As for washable, I personally don't put water in any hoses because I've never had one that didn't rot over time, and I've used/owned a great deal of hoses.
The widest diameter hose on the HH website is the Velvet Rope hose. It's also around 7 feet long.
