Hypothermia is one leg of trauma's lethal triad — and in far-forward casualty care, passive insulation alone isn't enough while powered warming devices are impractical to carry and run.
How do you actively warm a casualty with no power, through a long evac?
The HPMK® is the answer field medicine settled on — the CoTCCC-recommended system that combines a reinforced, patented HRS outer shell with an integrated self-heating liner in one vacuum-packaged kit. The HRS provides the thermal envelope: a 4-ply composite fabric with a protected non-conductive reflective layer blocks radiant heat loss, wind, and rain, while a top-to-bottom tapered shape and built-in hood with fluid-absorption pad minimize air gaps to maximize isothermal performance. Continuous 1.5″ 360° hook-and-loop closures let a provider reach in for reassessment, wound checks, and IV maintenance without un-wrapping the patient. Inside, the self-heating, oxygen-activated liner needs no external power and sustains 10 continuous hours of dry heat — enough to hold patient temperature across the most extended evacuation timelines. Vacuum packaging compresses the kit to a 6.75 × 10.5 × 5.5″, 3 lb 8 oz cube for medic bags and aid bags; once opened, the HRS deploys to its full 78 × 43″ coverage, encapsulating the patient head to toe. Reinforced and weight-tested to support 250+ lb.
