This survival bivy exists for one reason—Search & Rescue teams kept seeing the same pattern.

Every backup plan families had needed power, fuel, or fire. When all three were gone, they had nothing.

TerraShell uses a reflective aluminized lining to reflect heat back to you, while the outer shell helps cut wind exposure and resist moisture.

So you can stay warm and safe without any fuel, batteries, or fire. 

No batteries, no parts to break. Dead‑simple design means you can count on it when you need it.

Find a sheltered spot — car, living room, basement, garage, or campsite. Designed to help you stay warmer in cold conditions.

Climb into the TerraShell bivy. 

TerraShell is built as a full‑body bivy for more coverage and durability.

When you’re stuck in the cold, the rule is simple: reduce heat loss.

That means three things at once:

1) Block wind
2) Reduce moisture exposure
3) Reflect radiant heat back toward you

Most “emergency blankets” do one. Maybe two.

TerraShell is designed to do all three in one compact layer—fast.

Same simple physics—compressed into something you can deploy in seconds, even when you’re tired, cold, and your hands aren’t cooperating.
