Tungsten, the metal, is known for its ability to add strength and hardness to steel. The Outdoor Research Tungsten II Pant on the other hand, is know for adding strength to your alpine adventures by promoting movement and weatherproof coverage. The VerticalX Eco insulation offers lightweight warmth for easy movement, while the 2-layer GORE-TEX laminate seals out moisture and wind while wicking sweat. Small details like the waist adjustment tabs, an avalanche beacon pocket, and reinforced kick patches on the ankles further encourage alpine adventures.
