This innovative survival bivy could save your life for a simple reason—it was developed by an expert who's been there...
Andrew, a Search & Rescue specialist who watched families freeze in their own homes because their "emergency blankets" got wet and failed.
TerraShell uses NASA-inspired "Radiative Mirror" technology that turns your own body into a furnace in seconds.
Each bivy is designed to send 90%of your body warmth back toward you and create a windproof, highly water-resistant shell around your body.
No batteries, no parts to break, stupid simple design means you can count on it when your family needs it most.
Find any safe spot—car, living room, basement, or ditch. It doesn't matter how cold it is outside.
Climb into the TerraShell bivy and zip it up.
As you rest, the aluminized lining instantly reflects your infrared heat back to you—creating a warm micro-climate in minutes.
Most cheap "space blankets" rip easily and are bright orange targets. Not TerraShell.
TerraShell is trusted by search and rescue teams, overlanders, and tactical experts who understand that "Cotton Kills".
While most cheap blankets absorb moisture and freeze, TerraShell creates a vapor barrier that keeps you dry and warm.
That's why first responders keep several TerraShells in their own homes, cars and go-bags and recommend it to their communities.
It's professional-grade protection designed for regular families. Those who prepare in advance are the ones who survive.
