Patagonia Red & Black Polartec Regulator Jacket

Has a few flaws: one spot on the back as pictured and one on right elbow Regulator® fleece insulation provides phenomenal compressibility, light weight warmth and moisture transport, whether used alone or as part of a layering system. The lofted hollow-core fibers of Regulator fleece insulation conserve body heat while allowing body moisture to wick uninhibited during sweat-inducing activity. They’re also lightweight and highly compressible for packing.
