The North Face Ecwt

This Ecwt was manufactured by The North Face Company for use by the military in extreme cold weather (ECWS) conditions. Now made by Eureka.

These tents have double wall construction to provide an insulated inside, while the outside layer reflects wind, ice and snow. The rain flies block all light.

Tent Body

1979 North Star

The Ecwt is like the North Star expedition tent, it just does not let in the glorious sunlight that the North Star is known for, even with the fly on. The North Star has a ventilation chimney which helps prevent the tent from stifling in cold weather conditions. This also draws in cold air from outside the tent, similar to an igloo.

The combat units have no top vent, and the stove hole has been moved near the door.  Poles are thicker. These tents have the right shape, and enough room inside for any positions two people want to get into, except standing upright.

North Face spared no expense in designing this mobile, flexible nylon military shelter. The versatile, semi-geodesic dome shape tent is rated for 4 persons with full combat gear. This amazing shelter provides rain protection and weather insulation and will withstand high winds and heavy snow. Definitely an overbuilt tent! The government cost is over $3800 each in bulk. This tent system is still on the cutting edge of technology.
