MikeWozwrote a review of Patagonia R1 Fleece Full-Zip Jacket - Men's on January 4, 2017
Familiarity: I've put it through the wringer
Fit: True to size
This is my go to piece for intense aerobic activity in colder weather. I usually wear it under a light soft shell jacket or rain jacket. Always warm and breathable even when running up a mountain face. Bought 6 years back and it has withstood the test of time.
