The 4-Person Sundome Dark Room Dome Camping Tent blocks 90% of sunlight (vs. a comparable Coleman tent) so you can put the kids to bed early or sleep in past sunrise. It also reduces heat inside the tent for more comfortable rest at any time. Downpour in the forecast? Enjoy superior weather protection thanks to an included rainfly and the tent's WeatherTec system, which uses welded corners and inverted seams to keep water from getting in.
