This jacket is a game-changer for cold-weather hikes. Lightweight, breathable, and surprisingly warm. Easily the best men’s fleece jacket for hiking I’ve owned.

I used the R1 on a recent backpacking trip and it performed flawlessly. Packs down small and layers well under a shell. Great technical midlayer.

Bought the Patagonia R1 jacket online last month and it’s now my go-to for alpine climbs. The fit is perfect and the odor control really works.
