Breathable ‘Space Blanket’ Bivy — Touted as the first “emergency reflective shelter with breathability,” the SOL Escape Bivvy from Adventure Medical Kits is a lightweight bivy bag made out of a crinkly reflective material (a “vacuum-metalized spun-bonded olefin,” according to the company).
The SOL Escape Bivvy weighs about 280g and packs up to about the size of a Nalgene bottle. It has a hood and a drawstring opening to seal it shut. The bag will sell for $50 in 2012 when the company ships to stores.
