Comments about Porta Brace PHP-2 Polar Heat Pack (Pack of 24):
We used Polar Heat Packs inside Polar Bear Insulated Cases from Porta Brace during filming in -25C for two weeks.
With 4 heat packs inside the insulated cases you keep your hands warm, and most importantly the batteries lasts almost as long as it does in normal temperature.
