"What Our Gearhead® Experts Are Saying: ""When temps drop and I’m still moving hard, this is the fleece I grab. It’s noticeably warmer than the R1, blocks wind better than most midlayers, and still breathes when I’m working. I’ve worn it hiking, biking, and as a daily layer, and it hits that sweet spot between insulation and mobility."" We rely on the R2 TechFace Fleece Jacket when cold conditions demand more warmth without sacrificing breathability. Patagonia took the proven performance of the R2 and reinforced it with a weather-resistant exterior, creating a fleece that thrives during high-output days in colder environments. The high-loft grid fleece interior traps heat efficiently while managing moisture as effort levels rise. A TechFace-treated exterior adds resistance to wind and light precipitation, extending its range beyond a traditional fleece. With a slim, layer-friendly fit and stretch throughout, this jacket moves naturally whether we’re climbing, hiking, or heading out on a chilly evening."
