 "However, one of the armor's most lasting features was the T-shaped visor that adorned the helmet's face across its various incarnations. Numerous materials were employed in the creation of Mandalorian armor through the millennia, from alum and durasteel, to stygian-triprismatic polymer and the nearly indestructable beskar iron. Mandalorian armor forged from beskar was highly prized for its incredible resilience, and while sets of armor were often passed down from one generation to the next, beskar armor was considered the most valuable. The appearance of a Mandalorian's armor was largely up to the individual, as the highly independent Mandalorian people customized their armor with different colored paint schemes, clan and unit sigils, personalized glyphs, or other marking patterns in accordance to their own tastes."
