The Tungsten UL 4-Person 3-Season Tent is Marmot's largest backpacking tent in Marmot's ultralight Tungsten series, and unlike most ultralight tents, the Tungsten boasts a surprising amount of internal space. Marmot's Zone Pre-Bend Construction actually creates vertical walls to create more space instead of traditionally tapered walls. The tent's 3-season versatility includes a weather-resistant fly and floor as well as a full mesh canopy to keep ventilation at an all-time high in the summertime.
