Men's R1 Air Zip-Neck Fleece

The Patagonia Men's R1 Air Zip-Neck Fleece is a lightweight, highly breathable technical fleece with a half-zip neck opening, designed as an active midlayer for skiing, ski touring, and other high-output mountain activities in cool conditions. Like the Women's R1 Air Jacket, it uses a 100% recycled polyester jacquard fleece with hollow-core yarns arranged in a zigzag pattern that actively promotes airflow and moisture transfer, making it one of the most breathable technical fleeces available. The zip-neck configuration gives it a slightly more streamlined profile than the full-zip version, reducing bulk at the chest when layering beneath a shell.

The slim fit is designed for close, comfortable layering beneath ski jackets and snowboard shells without restricting movement or creating pressure points. Off-shoulder seams lie comfortably beneath pack straps and harnesses. A zippered left-chest pocket provides secure storage for small essentials. Quick-drying woven binding at the back hem and cuffs improves fit and durability over time.
