Shed weight without sacrificing performance with The North Face's Summit L5 LT FUTURe LIGHT™ Pant. Designed to excel in high-alpine environments, it perfectly balances durability, weather protection & lightweight construction, achieved through the use of their pioneering FUTURe LIGHT™ fabric technology. The most advanced breathable-waterproof outerwear material available, complemented by 3D ergonomic patterning for optimal mobility, finished with a streamlined feature set, should make it the first choice for your next summit assault.FUTURe LIGHT™ is made with a Nanospinning process. The Nanospun fibres create Nano-level holes to allow for impressive porosity while still maintaining waterproofness, letting air move through the garment & provide more venting in the fabric than ever before. Through Nanospinning, weight, stretch, breathability, durability & construction can be adjusted, to achieve optimal activity-specific performance.
