This chainmail haubergeon is constructed from thousands of butted flat rings. The rings themselves are 10 mm in diameter and 16 gauge in thickness and are constructed from mild steel with a blackened finish. The armpits are actually riveted to strengthen this area and prevent butted links from being pulled apart when the arm is fully outstretched.
The haubergeon photographed is a size large. It is a size that is a bit large on the mannequin and this explains why it may appear larger and looser than would be ideal.
IMPORTANT SIZING TIP: To accurately measure whether you will comfortably fit into this coat of mail it is necessary to first wear the clothing or padded gambeson that you intend to wear beneath the chainmail. Then measure your chest size over these additional layers. This way the additional width of your chest with these accumulated layers is accounted for when determining if the mail will fit properly.
