Product details

The Women's Classic Thermal Merino BL 1/4 Zip Boxed by Smartwool is a high-quality base layer designed specifically for cooler temperatures. This long-sleeve merino underwear offers optimal freedom of movement and high wearing comfort thanks to its raglan sleeves. The practical half-zip allows for customized ventilation, while the breathable properties of merino wool ensure a pleasant skin climate. The combination of 100% merino wool not only provides excellent thermal insulation but also natural odor control, making it ideal for longer outdoor activities. This underwear is particularly well-suited for sports such as hiking, trekking, and skiing, as it regulates body temperature while wicking away moisture. The flat seams minimize friction and enhance comfort, making it perfect as a base layer.
