The chest armor and spaulders were mostly metal, but the left spaulder appeared to be made out of a light type of stone, while the vambraces and greaves were completely leather. The armor set consisted of both metal and leather. This did not seem to affect Ezio's mobility, however. However, these layers acted in a similar fashion to a kilt, completely covering the legs, whereas the Master Assassin robes parted at the sides and front-to-back to keep movement unencumbered.
The bottom of the robes featured three layers, one overlaying the other, and came down to Ezio's knees. The armor came with a gray, short-sleeved robe that was worn underneath the breastplate. In Armor of Brutus, the emblem was engraved onto the back of the armor. One silver eagle decorated the right shoulder, holding the cape in place, while another adorned the belt where Ezio's other outfits featured the emblem of the Brotherhood. It was unknown when the fur was added, but it may have been a tribute to Romulus by his Followers. The armor looked much heavier and bulkier than Ezio's Master Assassin robes, due to the fur cloak that was padded along the pauldron and around the neck of the hood.
