Patagonia R1 Thermal Jacket - Men's Black, L

What Our Gearhead(R) Experts Are Saying:"This version of the R1 feels sturdier for real alpine use. The outer face sheds wind and snow better than typical fleece, and the micro-grid interior breathes incredibly well on the move. It's slim, layerable, and great for climbing, touring, or cold-weather hiking."Cold air sweeps down from the ridge and the R1 Thermal Jacket stays steady against the shift. A smooth, weather-resistant face fabric blocks gusts and loose flakes, while the micro-grid fleece interior traps warmth without slowing high-output movement. Every reach, scramble, and switchback feels free thanks to the stretch-friendly Technostretch build. Low-profile pockets stay comfortable under packs or harnesses, and offset shoulder seams prevent rubbing during long pushes with heavy gear. Tuned for efficiency in exposed terrain, this layer transitions seamlessly from technical ascents to fast approaches and crisp backcountry laps.
