Patagonia R1 Air Jacket - Men's

Hollow-core recycled fleece breathes hard enough to keep pace on steep cold-weather sends

The Patagonia R1 Air Jacket is built for the moments when a standard fleece becomes a liability: the sustained climbing pitch, the skintrack, the long ridge traverse where output stays high and stopping isn't an option. The jacquard weave and hollow-core yarns dump heat and moisture faster than a solid-knit fleece, so the slim fit stays comfortable against the skin instead of clammy. The hip length and single chest pocket keep the profile clean under a harness or a shell.

What Our Gearhead® Experts Are Saying:

"I wear this on the approach and keep it on through the crux. The hollow-core yarns move heat out fast enough that it never turns into a sauna under a shell."

Men’s R1® Fleece

Dialed for cold-weather movement, the R1® is a breathable, moisture-managing midlayer built to handle high output without overheating. Lightweight and packable with a performance-first fit, it’s the layer you trust when the pace changes but the objective doesn’t.

Zigzag Jacquard Fleece Knit

The R1® Air Jacket uses a zigzag jacquard fleece knit engineered to move air as efficiently as you move. This open, textured construction creates built-in channels for heat and moisture to escape, delivering exceptional breathability during high-output efforts. Lightweight hollow-core yarns trap just enough warmth while drying fast, making this fleece ideal for cold days when you’re climbing, skinning, or moving nonstop.
