Having a packable, lightweight emergency bivvy could be a life saver. A pleasant day hike can turn into a cold wet adventure with a change of conditions. The Emergency Bivvy has sealed seams to protect you from wind, rain, and snow while reflecting 90% of your body heat back to you. The bivvy is large enough to use as a sleeping bag cover if needed. The bivvy includes a rescue whistle and a tinder cord drawstring which can be used to start a fire. The polyethylene material is tear resistant and water resistant. The bivvy takes up about the same space as a soft drink can. It is easy to be prepared for the harshest conditions with the Emergency Bivvy.
