Quirinus Tech is a Human manufacturer of protective armor, known for using advanced flexible weaves and alloys to produce lighter pieces that match the stopping power of more traditional materials, albeit often at a higher cost. Because of their streamlined appearance, they are often used by private security firms who wish to maintain a lower profile. Roberts Space Industries (RSI) partnered with Quirinus to include their Calva helmet with the initial launch of the Mantis interdiction ship.
