Being slightly larger, the Sundome 3 can sleep 3 people with a floor space of 7' x 7' and centre height of 52". The material of the tent flooring is 1000D Polyethylene and the tent cover is 75D Polyester Taffeta. The tent walls are made from Coleman's Exclusive WeatherTec System that is guaranteed to keep all water out. Like the base model, the Sundome 3 features 1 door, privacy vent windows, an electrical access port, and adjustable Variflo ventilation. This model comes with a limited 1 year warranty.
This model is fairly small and low priced, making it a good tent couples who want more space than the base model, but not to pay much extra. All tent fabric is coated in 450mm PU Coating to assist in keeping the tent weather proof. The Sundome 3 comes with a carry bag that includes separate bags for the poles and stakes. The colour of the tent is in shades of grey and orange.
