RapidTHAW heated blankets are constructed of tough reinforced PVC, grommeted around the perimeter, insulation is provided by a closed cell microfoam which keeps the heat directed to the ground or snow, and all edges are sealed to keep out the elements. These durable blankets are reusable, roll easily and store compactly, ready for the next storm.

RapidTHAW blankets do not require a thermostat. Blankets run full-throttle and maintain a consistent temperature beneath the blanket of 60°F above the ambient air temperature.  Adding a second insulated blanket on top is strongly recommened for maximum results.
