Looking for ideas

I have a small box I want to insulate, about 24”x 24”x 24” made of 3/4” pine.

I would like to attach 2” rigid foam to the outside, but then wrap that with something weather proof so that the foam is protected and won’t chip off etc.

Lightweight, simple to install, nice looking, and not crazy expensive would be nice.

Something like a thin vinyl sheet with corner and edge trim would be ideal, but I’m not sure what to search for.

Any thoughts on durable products?
