TacMed™ Notfall-Biwak

How does the TacMed™ Emergency Bivvy compare to a standard space blanket?

The TacMed™ Emergency Bivvy is significantly more durable and provides superior thermal protection compared to a standard mylar space blanket. It features a heavy-duty outer shell (coyote brown for concealment), an interior heat-reflective thermally efficient coating, and Velcro head-to-toe closures that fully enclose the patient — addressing all four mechanisms of heat loss simultaneously. Standard foil space blankets only address radiant heat and tear easily under stress.

What makes the TacMed™ Emergency Bivvy suitable for tactical operations?

The coyote brown exterior provides visual concealment, unlike orange or silver blankets that can compromise operational security. The heavy-duty material resists tearing under rough field handling, and the 5.5 × 2.5 inch pack size allows carry in a cargo pocket without sacrificing significant kit space. It deploys in seconds without tools or assembly.

Does the TacMed™ Emergency Bivvy provide head coverage?

Yes. The Bivvy features head coverage and Velcro closures that can be adjusted for a head-to-toe seal. In hypothermia prevention, covering the head is particularly important as significant body heat is lost through the scalp and face during environmental exposure.

Can the TacMed™ Emergency Bivvy be used to move a patient?

Yes. The heavy-duty construction of the Bivvy allows it to be used as a short-distance patient movement aid, providing thermal protection simultaneously with transport. It is not rated as a dedicated litter for high-load or long-distance carries, but it is suitable for moving a casualty across short distances in field environments.

How does the TacMed Emergency Bivvy differ from the TacMed HELIOS System?

The Emergency Bivvy is a passive thermal retention system — its reflective interior and heavy shell retain body heat without generating additional warmth. The TacMed™ HELIOS System is a modular active warming system that includes a Medi-Heat air-activated heating pad (in the Active Warming variant) that generates heat to actively warm the patient. For prolonged field care or casualties in deep hypothermia, the HELIOS System's active warming capability offers a higher level of thermal management.
