The Patagonia R1 Ultralight 1/2-Zip Pullover is the lighter and more breathable member of the R1 family, designed for high-output mountain activities where efficient temperature regulation and low weight are essential.

The fabric is a 4.6-oz flat-faced double-knit, made from 100% recycled polyester. Its construction provides comfortable warmth and next-to-skin comfort while the smooth outer face offers improved abrasion resistance when worn with a backpack or around rock and technical equipment.

The pullover features a Slim Fit that follows the body and makes layering easy. The design is optimized for freedom of movement and comfort during climbing, hiking and other technical activities.

A deep 1/2-length center-front zipper allows rapid ventilation and easy temperature regulation. The unique single-panel sleeve construction keeps seams off the shoulders, improving comfort when carrying a backpack.

Vertical chest pockets provide convenient storage for a phone, map, snacks or other small essentials without adding unnecessary bulk.

Low-profile cuffs provide full wrist coverage and can easily be pushed up over the forearms. The longer hem is designed to stay tucked underneath a harness or other technical equipment.

At just 240 g / 8.47 oz, the R1 Ultralight is ideal as a lightweight standalone layer or as part of a technical layering system. It is made in a Fair Trade Certified™ factory.
