Mmmmmmm, Im not taking a warm jacket. On the course in sweden i went on, everyone was given the m90 jacket greger suggested.My mothership jacket, will be my jerven bag, which I can also use as a survival shelter, bivi bag, all sorts.
I have a thin cotton very baggy anorak, with a coyote fur ruff. An Austrian dachstein cardigan. 400 power ulfrotte top. 200 ulfrotte top. 200 devold top. three thinner 160 merino tops.[pack down smaller than T shirts these, more of a sanitary layer] 200 woolpower long johns. 200 merino icebreaker long johns. non cotton boxers. 2 pairs liner socks, probably 5 pairs of swedish army wool socks. Im most upset about having to leave behind my ash and rawhide snowshoes. But they are just too long.
Swedish m39 woolen trousers, and swedish surplus cotton overtrousers. N1-b mukluks, and after about 3 years searching ive found brilliant pair of latex motorbike overboots. Also taking a pair of sorel caribous.
Hats, Ive got a rabbit fur ushanka, [but mines a woolrich one, not ideal, as its lined. A cheaper, russian unlined ebay one would breathe better]
Smartwool thin beanie, normally paired with merino buff.
Merino possum hat from mears shop, with a merino possum buff. [I like to wear this as a headband, when i moving or exerting myself] And a woolpower balaclava which i sleep in.
Got other hats, but thats what im taking. I'd like to take more, but i just dont have the luggage space. For instance a -30 rectangular footbox wiggys ultima thule bag with a hood, almost fills an entire deployment bag about 80 litres, when compressed.
Browsing through the black friday sales, Ive seen all sorts, canada goose for £300, Fjallraven arctic parka, half price £300....etc. If youre gonna spend that If it was me, Id get the £280 extra king size jeven thremo, because you can use it to drape over your hammock, over here, make a tarp out of it, just get in it, bivvy bag, jacket, sleeping bag, but you might not like it, dunno. [They tend to hold their value well]
Id hire or go with Gregers suggestion Dewi if you dont want to spend hundreds. [I think there are two types of m90 jacket, one with a built in hood?]
I think Chris is getting a top of the line Rab down jacket, his kits gonna weigh half mine! And Ash has got a fjallraven down jacket with g1000.
