Windproof and stretchy but modestly insulated, Lightweight better suits high-output endeavors in blustery weather than its burlier R4 counterpart. The unlaminated R1 underarm panels enhance breathability, while seamfree shoulders improve pack-wearing comfort. When full conditions roll in, the contoured cut easily accommodates a shell. The women's version has feminine shaping and a two-way front zipper. Made in USA.
