Has anyone tried the Bolle Ultim8 goggles? They are only ANSI Z87.1-2010 / ANSI Z87.1-2015 /Z87+ rated, but are D5 when worn with the retainer strap, and can take a prescription. I am wondering whether folks think wearing them under a full face respirator would provide enough protection from tear gas and projectiles. EDIT: prescription lenses will be ANSI and impact rated.
