Skinbalm based on fat. The swedish army has its own version.
Why?
Because soldiering= being outside basically all the time. And being outside 24/7 at freezing temps will make your skin especially lips and around the nose dry out. It can go so far that you actually bleed and hurt when you breathe. It sucks- and unhappy freezing soldiers who cant even breathe without hurting wont be fighting at their top.
The one in the link is pricy though. But its good and its edible as well- can be used to fry food in you lack cooking oil/ fat. If you substitute it for another brand go for one WITHOUT water as an ingredient. Stuff with water will just make it worse.
