I have used custom fit shades from Covercraft (folding) and WeatherTech (rolled). Both are well insulated and I have not found them too hot to handle, at least on on 90+ degree days. They are roughly half the price of the OEM offering. I find the Covercraft is easier to install and remove, while the Weathertech provides a tighter fit covering every bit of glass. I do use the OEM transparent shades on the rear side windows. They offer marginal benefit, blocking a bit of light but not much reduction in heat transfer. As any meaningful level of window tint is prohibited in my state, I choose not to take the risk.
