The SOL Emergency Bivvy OD Green with Rescue Whistle will help you survive outdoors in the cold in an emergency. This compact, lightweight bivvy weighs less than 4 ounces and is smaller than a soda can, fitting easily in any backpack, purse, or car. The emergency bivvy reflects 90% of body heat back to you with the sealed seams and waterproof material. It traps warm air to prevent heat loss and keep out rain, wind, and cold. The material is also ultra quiet and tear-resistant and will not shred to pieces if punctured. Included with the reflective bivvy is a tinder paracord drawstring for fire starting and a survival whistle to signal your location to rescuers. Ultralight and compact, the Emergency Bivvy is a potentially life-saving addition to your gear that’s designed for emergencies.
