There are Rain-coats in the game already, although I'm not sure how much it stops you from actually getting wet, but if being wet/cold did something to increase calorie consumption then all of a sudden you're increasing food supply and not demand, cue tension amongst starving groups without raincoats and not enough to feed everyone. Pretty authentic zombie experience to me. You could say the same for snow. You could run around in Full-Mil kit with an M4 and die of exposure or you could forego the protection of ballistic helmets and stab vests for an ushanka and a puffer jacket and be out in the cold looting frozen corpses. It'd be a tossup between a scavenger and combat path really. Supply and demand based on things like weather creates value where there was none previously. You loot any corpse on a server these days I imagine you'll find guns, ammo food and maybe some medical supplies, but nothing else, and I think this will change as more features are implemented. You'll start to find hunting snares, gas stoves and anti-biotics when they actually serve a purpose, I'm not sure why the same shouldn't apply to clothing designed with specific weather conditions in mind?
