Whether worn as a warm midlayer on fall trail runs, a heavyweight baselayer on cold days of skiing, or as a cozy top for post-adventure relaxing, the Vertex Long Sleeve Half Zip Flurry is a versatile favorite. Made from warm, stretchy and incredibly soft merino wool with a cozy jacquard knit, the Vertex features a zip-neck design that lets you easily adjust to changing temperatures. Offset, flatlock seams prevent chafing when you’re wearing a pack, and the droptail hem offers additional coverage.
