As to a good type of material for a capote or great coat, I found more information that you may find interesting:
“As for fabrics, only sheep's wool is appropriate. The fabric weight can only be a rough guideline: A densely woven, well-felted, light woolen may keep out the cold and the wet better a heavier, less densely woven and/or less felted one. Worsted is not suitable because it lacks the insulating effect of felting. I strongly advise against any twill weave because they are often elastic on the bias”¦”¦. If the fabric is well-felted, the edges can be left raw.”

The following is information on material, but also on using the collar to protect much of the face in bitter cold by folding it up ”“ as opposed to having a hood. Good pictures in the link that demonstrate it:
“Fortunately, Tailor Mark Hutter of Colonial Williamsburg obliged us by showing us his handsome great coat, typical of styles from 1740-1770. Working from extant 18th c. examples as well as portraits, Mark made this double-breasted coat, right, from grey wool beaver cloth, a dense, fulled (think felted) fabric that is napped and pressed to resemble beaver fur. The cloth was thick to be wind-proof, and rain and snow would find it a challenge as well. Because this is an overcoat, the body is unlined. The buttons are covered with the same cloth, and the buttonholes are welted.”

Since some Navy Pea Coats go back to the early 18th century, I thought it might be good to see what kind of material they were/are made from.
The standard for historical pea coats was 30 ounces (approx. 850 g) wool, most often made of heavy Melton cloth through the 1970s in the U.S. Navy. Presently coats are made from 22”“32 oz (620”“910 g) wool.

“Melton cloth[edit]
Melton Mowbray is home to Melton cloth (first mentioned in 1823), which is the familiar tight-woven woollen cloth which is heavily milled, and a nap raised so as to form a short, dense, non-lustrous pile. Sailors' pea coats are traditionally made of Melton cloth, the universal workmans' donkey jackets of Britain and Ireland and in North America, loggers' "cruising jackets" and Mackinaws.”

Another choice to protect much of the head when one does not want a hood as part of the coat is the separate cloth hood shown in this Kannik’s Korner pattern:
