The Chimera project started of with the following design challenge: Designing a switchable CBRN (chemical, biological, radiological, nuclear) protective suit for soldiers, one phase being a regular work state and the other phase being a protective state to enable the soldier to get away from the toxic area within an hour. The switchability was solved by creating a suit which is partially opened and will be closed in times of a chemical attack. The openings are shaped like hexagons to assure the best flexibility and biggest surface area opened in total. The non-opened part of the suit will be made of impermeable material, using a layering of the best materials available for impermeability (Microchem 4000), for fire resistance (Nomex) and absorption of sweat (cotton). These materials are selected because of their technical specifications and are tested on comfort qualities.
