The Arc'teryx Men's Morphic Zip-Neck Top functions as a second skin, that is, if your skin evolved to be way more awesome than average. Its brilliantly engineered and lightweight Enduraflex and Phasic AR-X fabrics wick moisture, dry quick, and allow air flow, minimizing odor retention and virtually eliminating water absorption. Since the Enduraflex material contains a touch of spandex, the Morphic fits your shape perfectly and flexes with each movement. The Phasic fabric, with an impressive UPF rating of 50, protects your skin from short term burn and from long term skin damage runs or hikes in sunny weather. Layer over this lightweight, performance skin for improved temperature regulation when ice climbing or slashing powder between groomers.
