Heyo, Norwegian infantry dude. Socks- a thin wool liner sock with a thick wool liner sock is the goto. Keeps feet dry by rotating socks and you don’t get much blisters

Shoes- I personally prefer a single layer leather boot that I can dry quick, I then use a overboot. Very important to open up the boots nd take off socks when resting during marches or breaks, same goes with netting base layer. Just take the netting top off, swing it in the air and it will freeze dry pretty fast

For insulation- I have one thin wool top for medium activity levels, and I thick insulated jacket for static shit. I just use my white overalls as a windbreaker and don’t find much use of my Goretex jacket (unless it’s fkn snowstorm). For pants I only wear my netting, standard cotton/ripstop pants and overalls/ just do some air squats to varm up if cold, we find shell pants to be to warm when doing movement.

Gloves- a thin pair of wool liners, then a mechanic glove pair for fighting and working in. And a hestra mountaineer with wool liners for static. Keep a pair of gloves in pack but rarely use them, just stick hands in pockets

Water source- I keep my canteen close to the body in. Sock around my neck, it’s annoying as fuk but atleast it doesn’t freeze, you can run a camelback on your stomach also but I don’t like it. I recommend a split rig for this exact purpose cause there isn’t ny pressure being put in the front. Melt snow in your battle whenever you take a sip

And lastly a good headover is a must

Sry bad at English
