The Trillium Worldwide Twi 1001N 12 Volt Heated Travel Electric Blanket is 100% soft high quality polyester fleece to provide comfort. It is designed to take with you on road trip, camping, even just laying around the ice cold house in the winter. It has a 30 or 45 minute timer with automatic shutoff so it will not get to hot and catch on fire. It is easy for taking with you on trip because you can plug it into the cig lighter and keep warm even you break down along the highway. I’m glad my family and I own this Trillium travel blanket.
