I used the Q-Core SL pad with the Summit Park bag in the Turon Valley in NSW in Spring, the temperature at night reached 0 degrees Celsius.
I weigh 117kg and sleep on my side.
I had the best nights sleep I've ever had in this pad, it's thick enough so my hip never touches the ground, no cold travel up it.
I didn't find it noisy or slippery, it's very small and light and fits well in the bag it
