>>1149042>>1149059I can recommend wool mesh underwear such as Brynje, some thick wool socks, maybe two pairs of socks (one thin, one thick), regular clothing, a wool pullover and a waterproof jacket, plus gloves/hat.
When hiking you'll get warm, mostly in the legs, so you don't need extra thermal pants, they'd easily overheat you on the move. Once stopping you'll need something to keep your legs warm though, so keep that in mind.
As for the sleeping bag, these ratings are mostly semi-fraud, since a) everyone has a different feel for the cold and b) they are extreme ratings, not "recommended" ones and practically bogus. I'd say go to the store, buy some cheap bivy bag, space blanket or thick trash bag (the black ones) and wrap those around your sleeping bag to stay dry and warm. Yes, you'll have some condensation, but you'll manage. It will keep the warmth in and is a cheap, short-term solution. Also make sure you got good insulation between you and the ground, the sleeping bag is nearly useless for that. A Thermarest Ridgerest mat is doing a very good job for little money, reflecting most of the heat back to you.
If you got tons of money to spend, go for a Jerven Fjellduken, you can overnight (wouldn't call it sleep) in that fucker in -40°C.
