Hypothermia is the silent multiplier in trauma. Blood loss, shock, and cold exposure drive the lethal triad — hypothermia, acidosis, and coagulopathy — and a casualty who can’t clot bleeds out faster. The standard HPMK is the CoTCCC-recommended answer for field rewarming. The NAR HPMK-I takes that platform into the cold: a fully insulated outer shell so the covering itself retains heat, independent of the active warming component inside.
In an alpine or arctic casualty, the reflective blanket buys you minutes. What holds the heat for the next ten hours?
The patent-pending HRS-I shell adds Climashield insulation to the 5-ply composite construction, so the shell traps heat on its own — not just reflecting radiant warmth but insulating against convective and conductive loss in extreme cold. Inside, a 4-Cell Ready Heat blanket replaces the standard liner with sustained, oxygen-activated dry heat across the body for up to 10 hours, with no preparation: it activates on exposure to air. A built-in insulated hood covers the head and neck, and 1.5 in. continuous hook-and-loop gives 360° access to reassess wounds without un-packaging the patient.
Provider scope: The HPMK-I is a passive/active rewarming and hypothermia-management device. Field rewarming should be applied within your scope of practice and local protocol as part of overall casualty care. This listing describes the device and its contents; it is not a substitute for accredited trauma or tactical-casualty-care training.
Why This Kit
Climashield insulation built into the 5-ply HRS-I shell means the covering retains heat on its own — the key upgrade over the standard HPMK for arctic and alpine use.
Built on the CoTCCC-recommended HPMK and aligned to updated CoTCCC hypothermia-management guidelines — the doctrinal standard, optimized for cold.
The 4-Cell Ready Heat blanket delivers sustained, even dry heat across the body for up to 10 hours — oxygen-activated, no water, no batteries, no prep.
Continuous 1.5 in. hook-and-loop opens anywhere for wound checks and line adjustments without exposing the casualty to fresh heat loss. Rated to support 250+ lb.

Who Fields It
Alpine, arctic, and mountain units where ambient cold actively works against casualty survival.
Cold-water and search-and-rescue operations where immersion and exposure drive rapid heat loss.
Prolonged casualty care in cold backcountry where extraction is delayed and thermal management is continuous.
Build It Out
Match the rewarming platform to the climate, or run the standard HPMK in temperate conditions.
The CoTCCC-recommended baseline for temperate-environment rewarming.
The insulated shell on its own to pair with existing warming systems.
Blankets, shells, and warming adjuncts for the full thermal-management line.
The Kit, Up Close
Insulated shell plus 10 hours of active dry heat — the CoTCCC-recommended HPMK platform, built for arctic and alpine casualties.
