Still got questions and opinions on this …..
You get pre-made units that velcro over, foam and a printed nylon type covering.

Zippers, velcro and poppers are all feasible though. . I suspect velcro is the easier way.
I actually prefer that coarse broad webbing, which is not seatbelt material and it allows you to navigate the bend and absorb the curve neatly.
As Phil said, the vinyl can look bit untidy.
I always wanted a thicker bar for looks, and the wrapped look achieved that in part.
Like this size.
