Crafted only for Hammacher Schlemmer, this is the cordless heated stadium blanket that provides warmth and comfort wherever you roam. Unlike old-fashioned electric blankets with bulky components and tangling cords, this portable blanket has thin, imperceptible wires and a lightweight battery pack that lets users stay warm and dry while moving freely. This durable blanket is made from a smooth, lightweight material that sheds water, making it ideal for outdoor sporting events, cold-weather activities, or a chilly airplane cabin. The blanket is generously sized, heats up quickly to a maximum temperature of 110º F, and has a handheld controller with three temperature settings for optimal comfort. Its rechargeable 4400mAh Li-Polymer battery pack provides 1 1/2-2 1/2 hours of heat (depending on setting) from a 3 1/2-hour charge using the included AC adapter. Machine wash. Gray. 61" L x 56 1/2" W x 1/4" D. (2 lbs.)
