When fast-moving, cold-weather ascents call for a lightweight, insulated, multi-functional shield against the elements, look no further than the Havoc. The slimmed down sister of the popular Chaos, the new Havoc is the ideal outer- or mid-layer for cold, wet, windy and frequently changing conditions. Lightweight and highly technical, the Havoc features warm PrimaLoft Eco 60g insulation behind a durable, weather-resistant/breathable WINDSTOPPER shell.
