The Women's [ak] Helium Power Grid Base Layer Pants are designed for comfort and performance, on the mountain. Offering ultimate breathability thanks to their grid-patterned fabric. The material pulls moisture away from the skin and dries quickly to keep you warm and comfortable. Softlock seams are smooth against the skin, reducing chafing and making them ideal for layering during long days in motion.
