When the temperatures start to get uncomfortable, pull on your 260 Tech LS Half-Zip women's shirt from Icebreaker and you're ready to go. The updated base layer made from medium-weight merino jersey fits snugly and gives you warmth and freedom of movement. It is soft, breathable and odor-resistant thanks to pure merino wool. Offset shoulder seams prevent pressure points under your backpack, while offset side seams and flatlock seams prevent any chafing, even during high-intensity movement. The zip offers you quick ventilation and easy layering. Perfect for daily adventures or multi-day tours.
