Smartwool W CLASSIC THERMAL MERINO BL 1/4 ZB Women’s zipper shirt: With the Merino 250 Zip T you decide when it's time to stop. The inner layer of Merino wicks moisture away from the body and regulates body temperature. You can wear it on its own or as a base layer in colder weather. The special First Layer cut prevents irritation and abrasions. Specifications: 100% Merino wool with a special double-sided elastic seam provides comfort, breathability, heat regulation and odour resistance; a 25 cm long zipper on the front with a lock in the slider to prevent undoing; fewer seams in the shoulders thanks to shoulder panels; flat seams prevent skin irritation or chafing.
