The Hauberk, which was worn over the gambeson, was the chief body defence.
The gambeson appearing below the chausses, but covering the chaussons of mail, forming an extra protection to the knee.
The gambeson is shown on Fig. 9, appearing beneath the edge of the hauberk just above the knee.
We find the names of the gambeson, hacqueton, and pourpoint, and sometimes the jacke.
The gambeson (or Wambasium,) was a quilted garment, used either alone, or with other armour.
The shirts of mail are edged with wide borders, which may or may not represent the under tunic or gambeson showing beneath.
The ordinary series of body-garments worn by the knight are the Tunic, the gambeson and the Hauberk.
Quilted garments were still worn, either as the sole defence or as a gambeson under the mail.
As the sole armour of the soldier, the gambeson is mentioned both by Wace and Guillaume le Breton.
The "Aketon" appears to be but another name for the gambeson.
