Canvas Camper Shell?

Long time lurker, first time poster. Wierd first post, I know.

Anyways, does anyone here have a canvas camper shell for their truck? 

If so, what do you like/dislike about them?

 

I’m getting a new truck and debating the hard shell or the canvas. I live in SoCal, so IDK how hot that black canvas top would get. 

 

Thanks
