Gas Transfer Liqui-Cel NB" 6 x 28

The SolaTec" AeroVest" is an emergency cold weather survival vest. It is insurance against the cold for unexpected and changeable weather conditions. The AeroVest" is small, light (just 2 oz.), and easy to use. It can fold as small as a small cell phone or pack of cigarettes, so it can be carried in a pocket, pack, or small survival kit. It consists of an inflatable two-layer metalized vest which is inflated with air for a third layer of insulation, which creates a thermal barrier. The inside metal layer reflects back 90% of your core body heat. The outside metal layer blocks the wind and rain. Just 2-3 puffs of breath per side inflates the eighteen air pockets with 98.6? air, to help prevent hypothermia. Fits sizes small to extra large and is intended for a single emergency use (although with some difficulty, it can be deflated and used again). Made in USA. Wt. 2 oz.
