Icebreaker 250 Vertex LS Half Zip Crystalline Women (XS Only)

A versatile favorite for cold-weather comfort, the 250 Vertex Long Sleeve Half Zip Crystalline is made from incredibly soft, 100% merino wool for natural stretch and warmth. Worn as a midweight base layer or warm mid layer, it’s equally high-performing on a trail run in mild weather, on a cold day’s skiing or for relaxing in comfort aprés-ski.

The merino fiber is naturally breathable and odor-resistant to keep you in your comfort zone, wherever your adventures take you, and the half-zip design lets you easily adjust to changing temperatures. The droptail hem offers additional coverage, while offset, flatlock seams prevent chafing when you’re wearing a pack.
