Survival Frog Tact Bivvy 2.0 HeatEcho Emergency Sleeping Bag – Ultra-Light & Compact

Compact warmth for unpredictable conditions

The Survival Frog Tact Bivvy 2.0 HeatEcho Emergency Sleeping Bag is a featherweight thermal solution designed for quick shelter and reliable warmth. Crafted from HeatEcho reflective polyester, it weighs just 4.8 ounces yet packs into an oversized stuff sack, so you can tuck it into a pack, glove box, or emergency kit without bulk.

Why this bag stands out

In emergencies, visibility matters. The bright orange exterior makes you easier to spot by rescuers, while the HeatEcho material reflects a large portion of your body heat back toward you, helping you stay warmer in chilly conditions. The design is reinforced with taped seams to resist moisture and wind, delivering a weather-ready barrier that remains compact enough for everyday carry.
