The Wenzel Ozzie and Harriet Double Sleeping Bag will keep you extra toasty on camping trips when the weather is chilly. Big enough for two, it features a plush micro polyester liner and a durable polyester outer shell for soft comfort and longevity. The washable sleeping bag is stuffed with 7 lbs. of insulation and can handle thermometer dips as low as 40°F. This bag can be used separately or zipped together. The zipper can be opened from inside by either person for minimal disturbance when one of you enters or exits the cocoon. The top edge of one sleeping bag is a few inches lower than the other to allow you breathing space while your back is fully protected.
