What Our Gearhead® Experts Are Saying:"I like this jersey for cool-weather rides when temps fluctuate. The merino regulates heat better than synthetics alone, so I stay comfortable on climbs and descents, and it doesn’t get funky after a long ride. The relaxed fit works well with pads and still feels casual off the bike."We reach for the Merino 3/4 Sleeve Bike Jersey when fall rides bring cool mornings, warm climbs, and fast descents. Patagonia designed this jersey to feel right at home on the trail and just as natural once the ride wraps up. The laid-back style blends trail performance with everyday wearability, making it an easy favorite for shoulder-season riding. The merino wool blend delivers natural breathability and temperature regulation, keeping us warm when the air is crisp and cool when effort ramps up. Recycled polyester adds durability and helps the jersey hold its shape through repeated rides. With naturally odor-resistant performance and a comfortable cut that layers easily over pads, this jersey is built for long trail days and post-ride hangs alike.
