TacMed Emergency Bivvy
A heavy-duty, full-body emergency shelter and casualty-warming system in a cargo-pocket package.
What is the TacMed Emergency Bivvy? A heavy-duty, full-body emergency shelter and patient-warming system from Tactical Medical Solutions. The exterior is coyote brown for concealment; the interior carries a heat-reflective thermally efficient coating. Velcro closures provide head-to-toe heat retention, and it deploys in seconds for hypothermia prevention or emergency patient warming. Folded pack size 5.5 × 2.5 in; open 48 × 84 in. SKU MEDTAC0026.

Why It Matters
Hypothermia is part of the lethal triad in trauma, alongside coagulopathy and acidosis — a cycle where each element worsens the others. In the field, heat loss from a trauma casualty occurs through conduction, convection, radiation, and evaporation, with all four mechanisms potentially active at once in austere environments. The Emergency Bivvy provides full-body coverage that addresses all four pathways: the heat-reflective interior reflects radiant heat back to the patient, the heavy-duty outer shell blocks convective wind loss, and the head-to-toe Velcro closure minimizes conductive and evaporative loss.
The coyote brown exterior supports operational concealment in tactical environments — a feature absent from standard orange or silver mylar blankets that can compromise position awareness. Despite its heavy-duty construction, the Bivvy folds to just 5.5 × 2.5 inches — small enough for a cargo pocket or patrol bag — and deploys in seconds by unfolding and inserting the casualty, practical even in confined spaces.
Unlike disposable foil blankets or thin mylar wraps, the Emergency Bivvy is built from a durable material rated for rough handling in mission environments, resisting the tearing and delamination that would compromise thermal performance. It can also serve as a litter pad for short-distance patient movement, providing thermal protection and transport simultaneously.

When to Choose the TacMed Emergency Bivvy
- Tactical Medics & TEMS Teams Managing Hypothermia Risk — the lethal triad (hypothermia, coagulopathy, acidosis) mandates active heat-loss prevention from point of injury. The Bivvy's reflective interior and velcro head-to-toe closure addresses all four heat-loss pathways in a 5.5 × 2.5 in cargo-pocket package.
- Law Enforcement & Military Units Operating in Cold or Wet Environments — coyote-brown exterior maintains low visual signature unlike orange or silver mylar alternatives that compromise OPSEC. Heavy-duty construction survives rough handling and litter transport without tearing.
- Prolonged Field Care (PFC) Scenarios — when CASEVAC is delayed, passive thermal management over hours prevents hypothermia progression in patients who cannot be actively warmed. The Bivvy provides sustained heat retention without power sources or chemical reactions.
- Patient Movement on Improvised Litters — the heavy-duty material doubles as a short-distance patient movement aid, providing thermal protection simultaneously with transport — a valuable multi-function capability for small teams with limited equipment.
TacMed Emergency Bivvy vs. The Alternatives
- vs. Standard Mylar Space Blanket (SOL, Grabber, etc.): Standard foil space blankets are single-use, tear easily, and provide reflective coverage only — no head closure, no wind-blocking shell. The TacMed Bivvy adds Velcro head-to-toe closure, a heavy-duty tear-resistant outer shell, and a fully enclosed design that addresses convective heat loss the open-blanket design cannot. For single-use emergency carry the mylar blanket is lighter; for mission-reliable thermal management the Bivvy is the correct choice.
- vs. NAR HPMK (Hypothermia Prevention & Management Kit): The NAR HPMK is a larger, more comprehensive hypothermia-prevention system with insulation layers and multiple components, suited for prolonged field care. The TacMed Bivvy is a compact single-piece passive shelter that deploys faster and takes up far less space — the right choice when casualty load and speed-of-deployment are the constraints.
- vs. TacMed HELIOS Active Warming System: The HELIOS system adds Medi-Heat air-activated warming pads that generate external heat — valuable for casualties already in moderate or severe hypothermia. The Emergency Bivvy retains existing body heat passively. For initial-response hypothermia prevention, the Bivvy is the correct first tool; HELIOS adds active warmth for extended care when a patient needs more than heat retention.
Frequently Asked Questions — TacMed Emergency Bivvy
Q: Can the TacMed Emergency Bivvy be reused after deployment?
A: The TacMed Emergency Bivvy is constructed from heavy-duty reusable material designed to withstand rough field use. Unlike thin mylar blankets that tear and delaminate upon first opening, the Bivvy is durable enough for training use and multiple deployment cycles. However, as with any clinical equipment used on a patient, inspection for structural integrity and contamination is recommended before reuse in a medical context.
Q: Why is the coyote brown exterior important for tactical operations?
A: Standard emergency blankets use orange or silver reflective exteriors that are highly visible — a safety feature for civilian rescue but a liability in tactical and military environments where maintaining low visual signature is critical. The coyote brown exterior of the TacMed Emergency Bivvy reduces visual contrast against desert and woodland terrain, maintaining operational security for teams treating casualties in contested environments.
Q: How does the TacMed Bivvy prevent all four types of heat loss?
A: Radiation is addressed by the heat-reflective interior coating that reflects the patient's own infrared energy back toward the body. Convection is blocked by the heavy-duty outer shell, which prevents wind from carrying away warm air near the skin. Conduction is reduced by insulating the patient from cold ground surfaces when the Bivvy is folded under as well as over. Evaporation is minimized by the Velcro head-to-toe closure that seals moisture-laden air near the body, preventing evaporative cooling. This comprehensive coverage is why the Bivvy outperforms open emergency blankets in cold, windy environments.
Q: What is the folded pack size and where does it fit in a kit?
A: The TacMed Emergency Bivvy folds to 5.5 inches × 2.5 inches — small enough to fit in a standard cargo pocket, an IFAK side pocket, or a patrol bag without meaningfully increasing kit volume. When unfolded it opens to 48 inches wide × 84 inches long, providing complete head-to-toe coverage for adult patients. SKU is MEDTAC0026.
