Default Best heat insulating material for passports

What material should I wrap my passport with in order to retain the heat when going on an overseas skiing trip? Outdoor temperatures may drop to 0F or even lower. Even if I put it in the inner pockets of my ski jacket theres still the possibility of exposing it to below freezing temp and damaging the electronic chip inside. Will aluminum foil work? I stay in a mixed dor so I must bring along with me all my valuables.

Same thing goes tom y small digital camera.
