Survival Frog Tact Bivvy 2.0 Emergency

The Survival Frog Tact Bivvy 2.0 emergency shelter works through reflective physics: the mylar lining bounces body-radiated heat back at you while the outer layer sheds rain and wind. This is the emergency shelter that search-and-rescue professionals pack because on the day someone is forced to overnight unplanned, this bivvy is the difference between hypothermia and survivable conditions.

Reflective Emergency Bivvy Sleeping Bag

The construction is a refined mylar design — thicker and more durable than flat emergency blankets while maintaining the pocketable packed size. The bivy format is more practical than a flat blanket: you can fully wrap yourself, and the structure resists wind instead of collapsing or blowing away. The reflective layer is the critical feature: it reflects approximately 90 percent of body-radiated infrared, which is how a thin piece of material keeps you alive through a sub-zero night. For backcountry solo hikers, emergency preparedness kits, and vehicle trauma bags, this bivvy is the weight-free insurance that could actually save your life.
