The Icebreaker Women's 260 Tech LS Crewe is an absolute must for outdoor activities in cold temperatures. Plus, the long-sleeved shirt is so versatile that you can rock it casually, when travelling or just every day if you just can't get enough of it whilst ski or mountaineering trips. It works well on its own or as a base layer under additional layers of clothing. It's made of merino wool, so it's naturally odour resistant and temperature and moisture-regulating. To ensure that nothing chafes or causes discomfort when you have a backpack on, Icebreaker has incorporated flatlock seams and offset shoulder seams as well. A great base layer for the cold - the Icebreaker Women's 260 Tech LS Crewe.
