Key Features

⚡ Extra-Thick HeatFlex™ Mylar

Made from tough, tear-resistant Mylar designed for real outdoor emergencies. Reflects up to 90% of your body heat to keep you warm in cold, wet, or windy conditions.

🛡 Built-In Hood for Full-Body Protection

You lose up to 10% of body heat through your head—this design keeps that heat in. The integrated hood is a unique feature available only from Don’t Die In The Woods.

💧 Waterproof & Windproof

Completely shields you from rain, wind, and condensation. Can be used on its own or to boost the warmth and protection of your existing sleeping bag.

🪶 Ultralight & Compact

Weighs only 7 oz (about the weight of a small apple). Packs down to a compact 2.5" × 2.5" × 3" and fits easily into any survival kit, glove box, or backpack.

💪 Reinforced Seams

Wide, reinforced tape seams increase durability and make the bivy reusable—unlike thin, disposable emergency blankets.
