1) Lamellar aventail is most protected, but a bit less mobile compared to other options. It can be reinforced with bosses in the center of the plates, as shown in the photo by the link provided https://www.sharukhanmarket.com/oriental-helmet
2) Fabric aventail used just to cover hidden protection. It’s best to combine with hardened dome 2 mm thick to reduce overal weight of the helmet. Most lightweight and cheapest option. Can be various in colors and decorated. Here is an example of two-colored fabric aventail https://www.youtube.com/shorts/D5x-IgUlNPY
3) Chainmail avental something between previous two options, so midle level of mobility and protection.
4) Possible combine chainmail and fabric aventails together. See an example https://www.sharukhanmarket.com/tunka-helmet/
5) Scale aventail is under development, so I have nothing to show you right now.
