The Vulcan OGIO Caliber 2.0 Long Sleeve Polo is made with a pique knit fabric. All that means is that it now has a textured look and feel to it, for an elevated finish. And don't worry it still has all the sweat-wicking, heat-battling benefits you know and love. Accelerate beyond the limits in this high-performance polo that pays tribute to your favorite jeans with its rounded, bartacked placket.
