Canadian army sleeping bag is the cold weather inside section (not the full arctic set with hood and canadian bivy issued in the army) down filler, bivy sack is USMC waterproof gortex with hood, excellent condition (best bivy sack I have ever seen), with this you can throw it on the ground and sleep if you like, this is serious bush kit. canadian army down bag is supposedly good till -20c but I cant guarantee that..i have slept in it with proper layers in 1-2c with no problems. i just dropped the price for a quick sale..
