Icebreaker 260 Tech L/S Half Zip Merino base layer (M, black) - Perfect for skiing, ski touring, mountaineering or hill walking in the wintertime - the Icebreaker 260 Tech LS Half Zip! In fact, it doesn't really matter what you're doing! This shirt is a great option for everyday wear as well. Why? Well, the base layer is made of pure merino wool, which is naturally odour resistant and temperature and moisture regulating. Plus, it comes complete with a half-length zip you can use for fresh air when you need it. The flatlock seams will prevent any unpleasant chafing, and the shoulder seams are purposefully offset so that you can carry a backpack without any issues. The offset side seams add to the overall comfort of the shirt. Have fun this winter in the Icebreaker 260 Tech LS Half zip long-sleeved shirt!
