"Training Headgears for Genesis 3 and Genesis 8" is a collection of three types of headgears for both male and female figures of Genesis 3 and 8 characters.
These headgears are equipped with several tools to enhance render; such as photorealistic Iray settings, D-formers for bringing hair inside the headgear,
Morphs for punch impacts to the headgear and D-formers for controlling the parts of headgear.
This is a prop that will be parented automatically to the head, and is not a conforming clothing with AutoFit enabled.
When you need to match the shape of your character's face, you'll be needed to customize the scale of headgear.
In most case scenario however, such hassle won't be necessary and headgears will get along with your character just fine.
I have attached a PDF document that shows you how to use provided D-former to bring your character's hair in to the headgear.
