When conditions deteriorate in the mountains, you’ll be glad for the Summit L5 LT FUTUReLIGHT™ Pant. Constructed from The North Face’s FUTUReLIGHT™ fabric, it blocks wind and rain while remaining ultra-breathable. Designed so you can climb without distraction, ergonomic patterning and a minimalist feature set make it almost feel like you’re not wearing them at all.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.
