Cut close with a flat lock seam construction for comfortable layering, the Ibex Shak Jersey is a natural alternative to polyester middle layers, featuring the right balance of moisture-wicking density for skiing, hiking and running in cold weather conditions. Significantly longer than most zippered pullovers, the Shak's front zipper extends halfway down the front of the jersey, so you enjoy more ventilation potential than most middle layers, especially if you're wearing it over a light silk shirt. The itch-free Merino wool knit holds the dye at the core of each fiber, so you won't have to hassle with color bleeds or fading.
