The Coleman 8-Person Instant Tent Rainfly Accessory lets you enjoy added protection from bad weather while increasing airflow inside your tent. Coleman tents are sealed strongly to prevent water from entering, which means campers can sometimes lose airflow when it starts to rain and they zip up the windows. That’s why this rainfly cover is designed to fit over the top of 14 x 10 ft. Coleman 8-Person Instant Tents (sold separately) to provide added rain protection while giving you the ability to open windows without having to worry about rainwater getting inside.
