The Patagonia Men's R1 Air Full-Zip Hoody is a technical mid-layer designed for high-exertion activities in cold conditions. It is specifically engineered to balance warmth with extreme breathability, making it a favourite for alpine climbing, ski touring, and winter trail running.
The standout feature of this hoody is its zigzag-knit texture made from 100% recycled polyester hollow-core yarns. This unique structure is designed to wick moisture efficiently and dry incredibly fast while allowing for significant airflow. Because it lacks a flat-faced exterior, it dumps heat quickly during intense movement, though this also means it offers minimal wind resistance on its own.
