The Patagonia R1 Jacket (Women’s) is a technical fleece midlayer engineered for breathability, moisture management, and unrestricted movement across a range of active outdoor pursuits. Designed by Patagonia, it blends performance fabric with thoughtful design to support dynamic activities — from cool-weather trail hikes and backpacking to aerobic climbing, ski touring, and fast-paced alpine missions. Constructed primarily from Polartec® Power Grid® fleece, the R1 Jacket offers an exceptional balance of thermal regulation and airflow. The grid-structured interior promotes efficient moisture wicking and ventilation, while its stretch-enhanced design allows freedom of movement through shoulders and arms without restriction. A women’s-specific cut ensures comfortable layering over base layers and under shells, and offset shoulder seams reduce friction under pack straps and harnesses. With a slim yet durable design, a full-length front zipper, and low-profile elastic cuffs and hem to help lock in warmth, the Patagonia R1 Jacket is a go-to midlayer for women who want high-output performance without bulk. Whether you’re moving fast on the trail, approaching a crux, or layering for technical conditions, it’s built to keep you regulated and comfortable.
