Experienced climbers know that condensation can be a real hassle at high altitude. Waking up to find the inside of your tent lined with frost is a pain in the neck, and a problem that highly breathable fabrics (even mesh) can’t completely eliminate. That’s why we created the Condensation Curtain™, a thin piece of nylon fabric that hangs lightly above your sleeping bag at night, and isolates your respiration in a small portion of the tent, eliminating frost build-up. The Condensation Curtain™ can be easily removed from the tent to shake off any moisture in the morning.

Sleep Tight Anchor Transfer™ (STAT™)

The STAT™ allows you to stay tied-in and dry while sleeping inside Tenshi™ on an exposed wall or in a precarious position on a big mountain. Traditionally, mountaineers run a line from their harness to an external anchor through an opening in the door of the tent. But this method compromises the weatherproofness of the shelter, and also creates slack during a potential fall. The STAT™ eliminates these problems with complete weatherproofness and a direct anchor line. 


Pressure Porting™ is a patent pending technology that dissipates wind loading on overhead vents. Small openings along the seam of the vent allow some air to escape when high winds fill the vent. An outer flap conceals these openings and prevents rain and snow from entering. Pressure Porting™ technology allows your tent to be well ventilated even during high winds.


ECT™ shelters are equipped with numerous guy-out points for strengthening the tent poles and shell during the worst conditions. The tents come with guy-out cords that can be attached to any of the guy points, equalized, and secured to a tent stake or other anchor.


Many ECT™ tents have large overhead vents designed to increase airflow and reduce condensation. Each vent is equipped with a small strut along the vent opening for easy adjustment from the inside. Vents can be closed during severe weather.



Internal pole wraps allow you to quickly set up your tent from the outside, and then take your time to secure the poles while protected inside your tent. NEMO’s internal pole wraps are designed to be easier to grab with gloves than traditional pole wraps because of longer pull tabs. Double sided Velcro® enables fastening to be done in either direction, minimizing setup time



When the weather gets rough outside, snow skirts are a special feature that help block wind from entering your tent. When weighed down with snow, they also protect you from snow drift and spin drift.


NEMO’s internal pole tents eliminate the need for any pole sleeves, clips, or extra hardware that can add ounces to your packed weight. Button snaps in the tent corners help seat the pole ends and keep them from shifting.
