Conquer extreme alpine conditions with this 3-person expedition tent, engineered for four-season performance in harsh mountain environments. The 40D ripstop nylon flysheet with 2000mm PU coating resists tearing and withstands heavy rain and snow. The 9.5mm 7000-series aluminum pole system with multi-crosspoint architecture provides exceptional stability against strong winds. The spacious interior (213×258×103cm) comfortably accommodates three people with gear, while the 105cm extended vestibule offers ample storage for packs, boots, and equipment. The double-layer dome design with a 3-pole crossing structure ensures high wind resistance. Ventilation features include dual side windows with aluminum support poles for condensation management and a full-coverage breathable mesh inner for airflow. The sleeve pole system simplifies setup, and the wrap-around snow skirt minimizes snow ingress and enhances thermal retention in high-altitude environments. Minimum weight of just 4.71kg (without stakes) makes it suitable for alpine climbing, mountaineering, ski touring, and year-round camping.
