P.O.S.H. is the best rope you will come across for bondage. It is made of spun polyester and is usually beaten per 3 strings. It feels as soft as cotton and is UV resistant.
The rope has a very high breaking strength so it is obviously great for suspensions.
It comes in various colors that are usually colored deep to the core.

It is spun polyester beaten into 3 strings.
It feels as soft as cotton and is uv-resistant. So the rope will keep its color for a very long time.

Highly recommended if you want to be both artistic and aesthetic.
