In 2007, SonicWall announced the acquisition of Aventail Corporation. Standards were sometimes worn under an aventail, or even a gorget, for extra protection. Unlike the similar aventail, it was not attached to a helmet. Spangenhelms may incorporate mail as neck protection, thus forming a partial aventail. The open-faced bascinet, even with the mail aventail, still left the exposed face vulnerable. The aventail extends downward to protect the face and the neck. The low end of the aventail was often shaped in a zig-zag triangular pattern (vandyked). A mail collar hanging from a helmet is a camail or aventail. The bascinet had a mail curtain attached, a camail or aventail, which superseded the coif. Sometimes, the aventail extended down to cover the eyes and the nose. A branded version of it is also sold by SonicWALL as "SonicWALL Aventail Advanced Reporting". By the late 15th century, the aventail had replaced the mail coif completely. By the mid 14th century, the aventail had replaced the mail coif completely.
