The midweight R2 Jacket is the most versatile of our Regulator tops: It perfectly balances the needs for light weight, compressibility and toasty warmth in a cold-weather midlayer, while providing the convenience of a fulllength front zipper. Details: Lightweight Activist stretch panels in critical flex areas (sides, inside elbows and wrists), droptail, zippered handwarmer pockets. Made in USA.
