I live in southern AZ. In the summer I'd love the open breeze of no sides or windows, but our desert sun demands a top. I've had fabric bikini tops on previous Jeeps, but the flapping, stretching, and sun-rot, make these inconvenient. I have an idea in my head, of a bikini style top, but rigid, made out of a desert sun stable material, however I am not having any success with internet searches. Has anyone heard of such a product, or will I be stuck self-fabricating this?
