Product DescriptionCo-designed by veteran mountain guide Mike Haugen and tested on Mount Everest, the Coleman Exponent Helios X2 is a four-season tent worthy of the most grueling conditions. Developed to withstand high-altitude environments, the Helios X2 is a two-person modified dome tent. It has a footprint of 87"x52", with two large D-shaped doors and two vestibules that are 8 square feet each. Center height is 41". The Helios tent features four Yunan Atlas Scandium poles; used in high-performance sporting goods as well as military and space applications, the scandium alloy is well-suited to tent poles that must stand up to demanding conditions. A shock-corded floating connector, tapered on each end, joins identical poles, eliminating the need for a fixed insert in either pole. This innovative design allows the poles to flex in an even arc with better distribution of stress, making them stronger and less prone to failure. Structural features include a combination of pole sleeves and quick-clips for quicker setup without compromising strength. Extensive pole coverage with multiple guy-out points provides “bomb shelter" strength to handle snow loads and high-altitude winds. The 70-denier nylon fly sports silicone and polyurethane coatings to increase resistance to wind and weather. Inside pockets provide a handy place to store gear.
