A trauma casualty in the cold loses heat fast, and hypothermia drives the lethal triad — worsening coagulopathy and acidosis. A reflective-only blanket bounces back radiant heat but adds no insulation and no active warmth.
What pairs active heat with real insulation for cold-weather field care?
The HRS-Insulated does both. Where the standard shell relies on its reflective layer plus a chemical liner, the HRS-I builds Climashield® insulation directly into a 5-ply shell — higher passive retention before any active heat is added. The included 4-Cell Ready Heat™ blanket is oxygen-activated and self-heating, sustaining up to 10 hours of continuous dry heat with no batteries, electrical connection, or microwaved gel — it begins warming the moment the cells meet air. Together, sustained active heat and enhanced passive insulation make a more thermally robust system than the standard shell, tuned for prolonged field care in cold environments. A built-in insulated hood covers the head and neck, 1.5″ continuous hook-and-loop gives 360° access and supports 250+ lb for packaging, and the whole shell is impervious to wind and rain. It ships vacuum-packed in a rugged pliable pouch with NAR Red Tip Technology® for fast, gloved, low-light opening.
System note: a passive-insulation plus active-chemical-heat hypothermia-management shell, part of the HPMK-I platform. Field hypothermia prevention is an adjunct to, not a substitute for, definitive rewarming and evacuation. Apply per unit protocol and training.
