Streamlined and protective, The North Face\'s Summit FUTUReLIGHT Pant is a must-have piece. Constructed from 3-layer FUTUReLIGHT, it gives durable, breathable-waterproof performance. Design to defy the challenges of mountaineering, you can ascend in confidence whatever the conditions.FUTUReLIGHT 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 and provide more venting in the fabric than ever before. Through Nanospinning, weight, stretch, breathability, durability, and construction can be adjusted, to achieve optimal activity-specific performance.
