BACKBONE EMERGENCY THERMAL BIVY

Emergency Thermal Bivy Sack

When you hunt big country, your pack needs more than comfort gear. It needs backup plans.

The Emergency Thermal Bivy Sack is a lightweight survival layer built for the hunter who may be miles from the truck when weather turns, darkness catches up, or a long pack-out turns into an unexpected night on the mountain. At just 4.5 ounces, it takes up almost no room in your day pack, but it gives you a critical layer of protection when staying warm, dry, and visible matters.

The reflective interior helps retain body heat, while the wind-resistant and water-resistant outer material helps shield you from rain, snow, and cold mountain wind. The bright orange exterior adds visibility for emergency signaling.

Use it as an emergency bivy, survival blanket, wind barrier, ground cover, rain shield, or backup shelter layer. It is not meant to replace a real sleep system, but it is exactly the kind of lightweight insurance every elk, mule deer, bear, and public-land hunter should consider keeping in their pack.

Whether you are glassing a basin, pushing through timber, packing meat after dark, or dealing with a sudden mountain storm, this bivy gives you one more tool to stay protected when the plan changes.
