Patagonia R1 Regulator pullover in a vibrant blue hue, designed for high-output activities in cold weather. Crafted from a breathable, moisture-wicking grid fleece fabric, this technical mid-layer features a quarter-zip neckline for easy temperature regulation and raglan sleeves for enhanced mobility. The signature R logo is embroidered on the sleeve, and the slim fit makes it ideal for layering under a shell or wearing as a standalone piece during shoulder-season hikes.
