Today it will be about how you avoiding getting cold. When your out on adventure, becoming cold will be the last thing you want to be. So here come some advice. Number one, never be sweaty/wet. Adapt clothing all the time due to you activity. 
Let’s start with your feet. Have you ever feeling cold even in a nice pair of winter boots? The reason can be that you use liner socks and a thicker merino sock. The problem here will be that the moister will stay in your boot. The moister make the feet cold. So change or apply to a pair thicker socks when your not on the move. Also consider to chose a boot with a number bigger as you usually wear (for winter use at least).
Ok, so now we walk up the body. Upper base layer you should use a thin merino layer. The less than 200 should be your choice -why you might ask. The reason is that is very easy to open up and get cold, and it will dry fast as well. If its cold you can use a thick but just the underwear in that case. But remember that 250-300 is not designed to handle a lot of sweat. Also use a base layer with a zipper so you can open up for ventilation and get rid of the moister.
So the mid layer, this layer shall just be used when you not are active. If its cold and you active you can use a vest.
Shell layer, Gore-Tex is good but not perfect. When you doing some real tough activity you know it want not being able to evaporate all moister out. The reason is that Gore-Tex is breathable when its not raining outside, and waterproof when raining outside. So make sure the jacket got armpit zips. Put the waist belt of the back pack under, and if it has along zipper in the side open it up.
Another good suggestion for keeping you warm can be to fill a camel back with hot water under you jacket. This will keep you warm for hours. Have you ever woken up with hard cold boots inside or outside the tent? Here’s a tip: Take two nalogen bottles with hot water and put them in your boots, this will give you more comfort…
Use of down booties can be nice. This you can use at the campsite but also on your feet in the sleeping bag.

To have materials that breathes are essential in cold conditions. Wool is perfect for that.
Do you like to have woolen innebots Bergman? Lundhags have several of them.
The inner boots from Lundhags are really good. Once in the beginning of my carrier in the army we used ”fotlappar” which is a early solution of this. The good tning is that you can have them in the sleeping bag to be dried and also to warm cold feet:-)
