Quick Overview

The Outdoor Research Acetylene is one of a new breed of Hybrid mapped garments. What does this mean? PrimaLoft® Eco core insulation is strategically placed on the front and shoulders of the garment with lightweight Radiant fleece on the arms and lower back. This means a light garment for wearing on the go in cold environments. Warmth down the front where you need it, stretch fabrics for comfort, and no unnecessary insulation on the back where your rucksack sits. Sizing Info
