In the olden days, before about A.D. 1000, the hauberk was a shirt of leather or quilted cloth, covered by overlapping metal plates like fishscales. Now, thanks to ideas probably gathered from the Saracens, it is a shirt of ring mails, a beautiful network of fine chains and links, in the manufacturing of which the armorers ("the worthiest folk among all villeins," declares Conon) can put forth remarkable skill. The double or triple links are all annealed. The metal is kept bright and "white" by constant polishing (a regular task for the squires), and Conon has one gala shirt of mail which has been silvered. These garments form an almost complete protection, thanks to long sleeves, a long skirt below the knees, and a hood coming right over the head and partly covering the cheeks. A few brightly colored threads are sometimes worked into the links for ornament, but the flashing sheen of a good hauberk is its sufficient glory. The widowed Countess of Bernon has sent to Aimery, as token of good will, a ring shirt belonging to her husband. The knight-to-be swears that he will never dishonor its former owner while he wears it.

Helmets have been steadily becoming more complicated, but most warriors still prefer a plain conical steel cap encircled with a band of metal which may be adorned with gilt enamel. It has also a "nasal," a metal bar to protect the nose. Helmets are usually laced to the hood of the hauberk by small leathern straps. Since even a light and well-tempered helmet is an uncomfortable thing, you seldom wear it until just before going into action. "Lace helmets!" is the order to get ready for a charge; and after a knight is wounded the first friendly act is to unlace his headpiece. By the early thirteenth century helmets are beginning to have closed visors to keep out missiles. But these visors are immovable without taking off the whole helm; and if they get displaced and the small eyeholes are shifted, the wearer is practically blind. The old-style open helm will therefore continue in vogue until the coming of the elaborate plate armor and the more manageable jointed helms of the fourteenth century.
