Patagonia

R1 Pant - Men's

What Our Gearhead® Experts Are Saying:

"These are my go-to for everything from skintrack warm-ups to post-ride chilling. They’re super breathable and the grid fleece keeps heat in without cooking me."

From early-morning trailhead starts to crashing by the campfire after a long push, the R1 Pants from Patagonia deliver the lightweight warmth and stretch we rely on in the alpine. These pants are crafted from 6.8oz Polartec® Power Grid™ fleece that’s soft next to skin and built for movement with a touch of spandex. The internal grid design traps warmth while enhancing breathability and compressibility, making them an essential midlayer for cold-weather missions.

We appreciate the R1 Pants not only for their performance but for their conscious construction. Made with 93% polyester—41% of which is recycled—and sewn in a Fair Trade Certified™ factory, they offer comfort with a conscience. Whether worn under shells for active layering or solo around basecamp, these fleece pants are a dependable addition to our cold-weather kit.
