Any ideas or materials to use i want it to be comfy and dry thanks

We used to have an avery quickset on a 14 -42 xpress, had the windblockers which is a good canvas layer, it was an excellent lite weight blind, not permanent like u requested but very good for the money

Thanks yea i have a scissor blind on it now and i grass it but i want more waterproff and wind block it works fine but if its rainning all day your gonna get wet and the canvas above ur head makes little pools then dump down ur back when u move a lil bit
