The TacMed Emergency Bivvy is a compact, pack-able emergency shelter designed for field use when missions run long and conditions turn against you. Built from a tough heat-reflective material, it measures 48 inches wide by 84 inches long — large enough for head-to-toe coverage — and folds down small enough to fit in an aid bag, go bag, or cargo pocket. The coyote brown outer surface provides field-appropriate concealment, while the interior heat-reflective coating retains body heat for hypothermia prevention.

Who this is for

• Tactical medics and combat lifesavers who carry aid bags and need emergency shelter that won't sacrifice space reserved for medical supplies.
• Law enforcement officers and first responders on call-outs that can extend from hours into overnight or multi-night operations in unpredictable conditions.
• Preppers and outdoors operators who build go bags and emergency kits around weight and volume discipline.

Compatibility with parent gear

The Emergency Bivvy is sized and packaged to integrate directly into standard aid bags, go bags, and cargo pockets. Its compact form factor lets it coexist alongside medical consumables, tourniquets, and other kit without displacing critical supplies. At 48 x 84 inches deployed, it accommodates a full adult body from head to toe.

Function

The bivvy functions as a personal emergency shelter and heat-retention device. The interior surface carries a thermally efficient heat-reflective coating that traps radiated body heat, slowing heat loss in cold, wet, or wind-exposed environments. Taped hook-and-loop closures along the opening seal head-to-toe for maximum heat retention. The coyote brown exterior blends with common field environments, reducing visual signature when shelter must double as concealment.

This product addresses field-expedient hypothermia prevention. For active hypothermia management devices, the TacMed Helios System is the purpose-built companion product.

Specifications

Frequently asked questions

What does this work with?

The Emergency Bivvy is compatible with any standard aid bag, go bag, or tactical cargo pocket. Its compact packed size is designed to fit alongside medical consumables without displacing them. Deployed, it covers a full adult body at 48 inches wide by 84 inches long.

Is this the same as a space blanket?

Not exactly. The bivvy format encloses the body from head to toe with taped hook-and-loop closures, rather than simply draping over it. That sealed construction retains significantly more heat than an open-wrap reflective blanket, especially in wind or precipitation.

Does the coyote exterior matter tactically?

Yes. The coyote brown outer surface reduces visual signature in field environments where a reflective silver exterior would compromise a position. For operators who may need to shelter in place or establish a casualty collection point, low-vis coloring on external gear matters.

Can this be used for active hypothermia treatment?

The bivvy is a prevention and passive management tool. For active hypothermia treatment, the TacMed Helios System is the appropriate device. Use the bivvy to slow heat loss; transition to active warming when the Helios System or equivalent is available.

What is the final sale / expiration notice about?

This variant carries a July 2026 expiration date and is sold as a final sale item with no returns accepted. Plan kit rotation accordingly and replace before the expiration date to maintain mission-ready status.
