Anti-Fog Visor with Opposed Vents

A skydiving head-protector which comprises:

• a shell dimensioned to fit on the head of a user, wherein the shell is formed with an opening defining a periphery to expose the face of the user when the shell is positioned on the head of the user;
• a lens dimensioned to cover the opening of the shell, wherein the lens has an edge and is made of a transparent material;
• and
• a means for supporting the lens on the shell and for spacing a first portion of the edge of the lens from the periphery of the shell to establish a first vent having a thickness “d” and for spacing a second portion of the edge of the lens from the periphery of the shell to establish a second vent having a thickness “d”, with the distance “d” selected to establish a substantially non-turbulent airflow from the first vent to the second vent during a skydiving activity.

A head-protector which comprises:

• a shell dimensioned to fit on the head of a user, wherein the shell is formed with an opening to expose the face of the user when the shell is positioned on the head of the user, the opening defining a periphery;
• a lens dimensioned to cover the opening of the shell, wherein the lens has an edge and is made of a transparent material;
• a band dimensioned to surround the opening of the shell along the periphery of the opening, when the lens is in its operational position covering the opening;
• and
• a plurality of posts spacing the band from the lens at points adjacent the edge of the lens to establish at least one vent.
