The Pace Flow Half Zip is a fitted midlayer built for high-pace outdoor activities, engineered with Polartec® Power Dry® Mesh to balance warmth, weight, and breathability. The open mesh construction vents excess heat when worn as an outer layer, while trapping warm air effectively when used beneath a shell. Made from 100% recycled and recyclable polyester with Bluesign® certified fabric, it sheds minimal microfibers compared to traditional fleece. A zippered chest pocket and drawstring hem add functional versatility for running, ski touring, snowshoeing, and cross-country skiing.
