The Mountain Hardwear Helion 2 is Mountain Hardwear's lightest two-person tent. At under 3.5 pounds, this tent will continue to offer the rugged weather protection and durability that users have come to expect in their Mountain Hardwear tents. Designed with three Atlas UL poles, Mountain Hardwear's Evolution Tension Arch system stabilizes the tent during high winds. The fly uses welded construction and taped seams to create a waterproof barrier that is as light as possible. PitchLight option: Set up the fly and poles with the Helion 2 Footprint an even lighter shelter.
