The Nano Puff® Vest was originally designed for climbers seeking a weather-resistant, lightweight, and packable synthetic insulation layer that could retain warmth even when wet and endure years of use. Those same qualities have since made it a go-to midlayer for a wide range of outdoor pursuits. Updated with fit refinements for enhanced mobility, it’s built with 60-g PrimaLoft® Gold Insulation Eco made from 100% postconsumer recycled polyester with P.U.R.E.™ (Produced Using Reduced Emissions) technology, plus a 100% recycled polyester shell and lining. This versatile vest is crafted in a Fair Trade Certified™ factory.
