What Our Gearhead® Experts Are Saying: "I always throw the Micro D Beanie in my pack—it's ultralight, crazy soft, and surprisingly warm for how compact it is. It’s perfect for layering under a helmet or just keeping the chill off during shoulder-season hikes. I love that it's made from recycled materials and dries quickly if I start to sweat." We reach for the Patagonia Micro D Beanie when we want to stay warm without weighing ourselves down. This featherlight microfleece beanie packs small, delivers soft-on-skin comfort, and breathes well enough for high-output pursuits on cool days. Whether we’re trail running in brisk air or chasing golden-hour views on a fall ridge, it keeps us cozy without overheating. Built from 100% recycled polyester microfleece, the Micro D Beanie wicks moisture, dries fast, and fits easily under a helmet or hood. Patagonia’s commitment to Fair Trade Certified™ manufacturing means we can feel just as good about how it's made as we do when we wear it.
