Share warmth and companionship when on a mountaineering expedition with the Grand Mothership expedition tent. The four-season tent sleeps up to 12 people, or you can sleep four and use the rest of the space for eating and planning. The Grand Mothership is made of tough, insulating 70D nylon, with an interior area that measures 140 square feet. The tent also stands 7 feet tall at its highest point, so you won't need to stay hunched over while walking across the tent to grab your maps. And thanks to the continuous pole sleeves and double grommet pole attachments, the Grand Mothership stands up to heavy winds. Other features include large D-style doors, sewn windows, and ceiling and door vents. Built to comply with Sierra's Green Effect program--an eco-conscious commitment on the part of Sierra to reduce costs and waste and grow programs to promote sustainable outdoor recreation--the Grand Mothership is an ideal choice for your next climbing trip.
