Icebreaker Women's LS Zip Shirts

Whether you want warmth for winter sports, stretch for cool-weather runs, or great-fitting comfort all year long, these Icebreaker women’s tops have a lot to offer. Made from a merino wool blend, they provide extra UV protection and prevent clamminess. Plus, they’re naturally antibacterial and odor-resistant, making them great for multi-day treks and any trip that calls for a light pack with fewer garments. This drop includes base and mid layers that vary by fabric weight, sleeve length, and head coverage (hooded or hoodless)—pick the one that suits your needs.

In all three easy-to-layer long-sleeve styles, core-spun fabric adds durability, bonded seams prevent chafing, thumb loops provide extra coverage, and strategically placed mesh panels increase ventilation. The Comet serves as a functional pullover for chilly conditions, while the hooded Terra is great for high-output days (complete with a handy stash pocket on the sleeve). Finally, the hooded, insulated MerinoLOFT Ellipse is ideal for windy ridge climbs and alpine hikes.

Light and breathable, the Aero has a flattering fit with a wide crew neckline and feels incredibly soft against the skin. Wear it at the gym, on the trail, in the yoga studio, or just around town.
