Core warmth and superb breathability come together in our R2 Vest. Built from quick-drying R2 fleece, it traps heat and breathes freely to keep you warm and comfortable across a wide range of conditions. We make the body of the R2 Vest from exceptionally warm, directionally knit Polartec Thermal Pro fabric, which is superlight, fast wicking, compressible, stretchy and soft. Along the sides, lightweight R1 panels, with HeiQ Fresh durable odor control, improve fit, mobility and comfort range. The technical silhouette and raglan shoulder seams allow the full range of mobility and provide smooth comfort, even when worn under a loaded pack. There's a pair of sleek handwarmer pockets and the interior has two drop-in mesh pockets. Fair Trade Certified sewn, which means the people who made it earned a premium for their labor.
