I use a silk bag liner. The theory is that silk wicks perspiration and spreads it over a bigger surface where it evaporates faster and thus cooler than perspiration evaporating off your body.
I'm not sure it makes any difference when the temp is 105*, though, but I;ve had good expereinces in the 80* range.
