What can I say? I haven't ever found reflective sheets to be of any benefit beyond stopping airflow, nor bubble pads. But they don't weigh much so there's no harm in experimenting.

IMHO you have to deal with conduction first, convection second (higher priority if using an air mattress or sleeping in a hammock) and radiation last. I don't believe Jardine and I agree on that last bit.

cheers,
