The Alchemy Equipment Men's Coldblack Denim Blouson Jacket isn't the grimy old denim jacket your grandpa used to wear to work. In fact, you could say that Alchemy Equipment has single handedly set out to change the way we think about and use denim with its Coldblack Denim Jacket. Made with a Schoeller fabric, the denim material is treated with a Coldblack finish that will actually reflect the sun's rays, so you stay cooler during those bright and sunny days. Inside the jacket is Schoeller's 3XDry technology, which not only resists water absorption, but also stimulates a cooling effect, so you don't overheat when the sun's out. The center front closure and two chest pockets are all secured through YKK Aquaguard zippers, ensuring a water tight closure to the jacket and the two external pockets.
