The Coleman Heaton Peak 220 is a 2-season sleeping bag for adults. The synthetic filling provides enough insulation for the summer and spring nights at the campsite. The straight blanket model ensures plenty of freedom of movement when you're sleeping. Thanks to the soft inner lining made of cotton flannel, you'll be nice and comfortable. Going on vacation with someone else? If you both have a Coleman Heaton Peak 220, you can zip them together.
