Category: Men's Synthetic Insulated Puffy Jackets & Pants

The new version of the popular all around synthetic insulated vest from Arc'teryx. Made with new synthetic Coreloft™ stretch insulation that still retains the majority of its insulation value when wet. This low-profile vest is very lightweight and is a great layering piece that adds extra core warmth to your clothing systems without impeding the ventilation through your arms. Stretch fleece side panels further breathability and provide a more low-profile fit when worn as a mid-layer underneath your outer storm shell or ski/snowboard shell.
