See, In Wildlands all the masks came with Balaclavas, and people wanted them removed. Now that they don't have them, people want them to be added. So maybe in the next game, since it's not going to happen in Breakpoint, they could make it so that the balaclavas is a toggable option for all face masks.
But if you ask me, every category should have some items with toggable options for customization, just like the bloused boots.
Shirts - rolled or full length
Pants, - toggle between different kneepads
Vest - wear battle belt or not.
Masks - balaclava or bare
smaller backpacks - straps or mounted to vest
gloves - display watch on right arm, left arm or none
boots - bloused or not.
Eye wear - clear, or tinted (light, dark or coloured)
Headsets - use rail mounts or not.
