A helmet that always fit perfectly. For all ages.
Converted from Sims Medieval, edited and adapted for Sims 4.
This is a hat-hair, with hair attached.
This means that you add the headpiece in Hats section - and the hair comes with it. Hair color is added automagically, if you change the hair color of the sim, the hair color of this hat-hair will also change. It's not a method that suits all hats. In the merged file there is a file called HairOverlay, and if you want to edit the hair colors, you do it in this file. The mesh for hair is in the hat file.
The kids' versions take their textures form the adult version - one merged file. Unmerge the files if you want to edit or remerge but remember to keep the files together.
