We’ve improved our revolutionary Armachillo® fabric with an evolution in cooling comfort – enter Armachillo Air Out Knits. Our ingenious Made in the Jade™ technology features microscopic bits of jade embedded in the fabric, dispelling heat on contact. But then we went one better with pique mesh knit construction, with tiny holes to ventilate as you hit the trail or pound pavement. Athletic styling with elbow-length raglan sleeves and princess seams keeps you plenty agile with ample room to reach. Finally, wicking, 4.1-oz. 92% nylon/8% spandex knit fabric pulls moisture away, and a special fabric treatment fights odor, too. Tell sweat and sear to scram with the Armachillo Air Out Collection.
