Patagonia Regulator Lite Long-Sleeve Top - Women's Black, 6

When the air is warm but the waters are still crisp, we zip into the Patagonia Regulator Lite Long-Sleeve Topto help retain body heat while we wait in the lineup. The FSC-certified natural rubber construction creates fewer CO2 emissions than neoprene in production, keeping both our core and our conscience cozy, while the strategically placed seams keep us moving freely, and the corrosion-proof zip holds its own in the water.
