There is a nice Canadian issue goretex bivybag i would love. One thing you are going to see a lot more of is northern military maneuvers near the pole now that we are not friends with Putin and global warming has made the area more habitable .
The CF makes some great winter gear.
Here are the mukluks I wear when it is -50 and I am doing 60MPH on a SKIDOO.
The woolliners are amazing and are great for around a winter camp on their own.


Here are the new issue goretex pants but I prefer the old 2 layer ones.

These fleece pants are the greatest thing an army has ever issued in the history of man including the 1911 and the brits rum ration.

They go under a pair of outer waterproof pants in extreme cold but are perfect on their own all winter.

Winter camping rules so long as you are well equipped. No bugs and no sweaty tents.
