~~~ MERGED ~~~
A small number of new clothing types to protect you from the elements:
long-sleeved shirt - same material as a tshirt, but with sleeves
arm warmers - light, comfortable, and warm
leg warmers - basically the same as the arm warmers
long underwear top - to match the current bottom piece
tights - to match the current under armor
union suit - which is both long underwear types in one convenient item
rain hood - to keep your head dry in bad weather
And one simple craftable-only item to protect you from danger:
armored fingerless gloves - requires very little resources, adds a little more protection
Git!
