Check this sight for the Can Back

http://www.can-back.com/

They looks pretty durable/userful... kinda expensive though, and doubt it would survive a roll :D

Y a I didn't think they wood be quite so expensive. I don't think it would survive a roll either but it is for my tow rig so If I roll I'm in trouble.

i have had my canback for over two years,, never washed it,, fabic still looks great,, windows,, well if u ever had a soft top vehicle u know what thats all about,,only complaints i have is loss of visibility when changing lanes,, got some blind spot mirrors,, also they bolt the canback to the bed rails,, i just use cap clamps,, make on and off easy when u go the junkyard to get big d60s.....
