TETON Sports 4-in-1 RV 40 Degree Doublewide Rectangular Sleeping Bag - This sleeping bag is perfect for the RV or any other time you want to share sleeping space with a loved one. At 80in long and 70in wide， it's the perfect size to fit most RV beds. The RV sleeping bag controls temperature by a thick and thin side to the bag. With the thicker side down， the temperature rating is +40 degrees. Flip it over with the thicker side up and， as long as you have some good insulation from the ground， the temperature rating improves to a cozy +20 degrees. If that's not enough features for one bag already， separate the top from the bottom and make two adult size individual bags measuring 80in long and 35in wide each. The two individual bags have roll up straps for storage or if you keep it all together as one large bag， there are 3 convenient roll up straps with buckles for easy storage and carrying. 

• Size: 80in x 70in 
• Shell Material: Polycotton
