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.

Layering

Layers are the instruments of keeping you dry, warm and using your energy efficiently. Put into the right systems, a good sequence of layers provides you with weather protection, moves moisture away from your skin, conserves or dissipates heat, and does this in the least amount of time.

Use the layering guide to select additional pieces for your system and understand how they fit together. Find out more about how to layer on our Layering Page.
