Sunrise to sundown, from epic approaches to alpine traverses, the versatile R1® Pullover stretches, breathes, moves moisture and insulates. Made of Polartec® Power Dry® polyester (41% recycled)/spandex fabric with a high/low grid interior, it provides enhanced breathability, superb compressibility and stretch, has a terrific feel and remains durable and warm. Sized to accommodate light underlayers, it works as a stand-alone top or as a light midlayer. This season we gave its curves a serious makeover, re-sculpting the pullover with a more feminine-specific technical fit. The smooth, microfiber face layers with ease, offset shoulder seams provide pack-wearing comfort.
