Grabber Outdoors Space Emergency Thermal Bag/Bivy 36"x84" Silver 6913SBEB

4 ounces of insurance against hypothermia — packs smaller than a deck of cards.

The Grabber Space Emergency Thermal Bag is a full-size survival bivy that retains over 90% of your radiated body heat. Taped seams and a collar design trap warmth more effectively than a flat emergency blanket, and the whole thing packs down to less than 4" x 3" x 2" — small enough to live in any pack, car kit, or emergency bag.

Key specs:

• SKU: 6913SBEB
• Dimensions: 36" x 84" (full size)
• Packed size: Less than 4" x 3" x 2"
• Weight: 4 oz
• Material: Aluminized emergency blanket material
• Retains: 90%+ of radiated body heat
• Taped seams for durability and insulation
• Collar design to trap heat at the opening

Why it works:

A flat emergency blanket loses heat at the edges and doesn't stay in place. The bivy design wraps around your entire body and seals in warmth, while the taped seams prevent heat from escaping through the stitching. The collar traps heat at the top so you stay warmer even in wind. Use it alone or over a sleeping bag for extra insulation in extreme cold.

Ideal for: Hikers, backpackers, hunters, overlanders, and anyone building a car emergency kit, day pack, or survival bag.
