Canadian Forces (CF) experience in the Gulf War (1991) confirmed that the current in-service individual protective ensembles (IPE) resulted in significant thermal stress and heat casualties when forces were operationally deployed in hot climates. In an effort to redress this deficiency, Defence Research Establishment (DREs) were tasked to determine the most suitable materials and garment designs for IPE wear in hot weather, in terms of both operational effectiveness and reduced thermal demand. A human factors (HF) evaluation plan was developed to investigate the suitability of state-of-the-art materials and novel designs with the CF army, navy and Air Force. Trial quantities were produced and evaluated by the DREs for chemical challenge and thermal demands. After preliminary testing and material modifications, a semi-controlled (HF) field evaluation of the In-Service and sixe prototype IPE designs was undertaken at CTC Gagetown in August 1997 to determine the most suitable HF design for future (CF) Land Force procurement. The prototype suits evaluated during this trial included the In-Service baseline, and Undergarment design with two different lining materials and a One-Piece and Two-Piece design both with two different lining materials.
