Nuclei Pant Men's
Description
Rock, ice, and cold. Alpine environments are ruthless. Made for these conditions, the Nuclei Pant is tough, packable, weather-resistant, and warm. 80g Coreloft insulates waist to knee, and a lighter-weight PrimaLoft Gold insulates the lower leg. Made from 100% recycled nylon, the Pertex® Diamond Fuse outer has a unique, highly durable diamond filament construction. Our abrasion-resistant Hadron LCP fabric reinforces the seat and lower leg and has a PU coating for added water resistance.
What's been updated: Updated with durable Pertex® Diamond fuse mini-ripstop face for lightweight durability and wind protection and acrylic-coated Hadron® LCP (Liquid Crystal Polymer) grid fabric reinforcements for durability and water repellency.
