Ute canopy window

Hi, I have a HD Toyota Hilux Alloy canopy that is about to get a custom-made canopy fitted. I'm looking for material to be a clear, fixed window for inside the headboard. It would need no be have some straight, & some curved cuts, be able to be drilled to allow fixing, withstand jarring during travel, & maintain a high see-through visibilty for some years. Security isn't a great issue, as there is already a steel mesh grille there.

What material would be the go for this - acrylic ( e.g. Perspex), polycarbonate (e.g. Lexan), safety glass, etc.?

Cheers.
