Icebreaker Merino 260 Oasis Half-Zip Thermal Shirt - Black

Thermal long-sleeve shirt in black. Made from a lightweight knit fabric containing 100% Merino wool, it works well as a base layer for outdoor activities, tourism, trekking, travel, and everyday use.

The sweatshirt is made entirely of Merino wool – a lightweight and soft natural fiber. The material offers a favorable weight-to-thermal-performance ratio and reduces the formation of unpleasant odors.

Merino wool helps maintain the right microclimate next to the skin. In lower temperatures, it reduces heat loss, and when the temperature rises, it helps wick away excess heat and moisture. For this reason, the sweatshirt performs well in a variety of activities and weather conditions.

A zipper is placed on the front, extending to the middle of the chest. It allows ventilation level adjustment and makes the sweatshirt easier to put on and take off.

When unzipped, the zipper increases airflow around the neck and chest, which helps wick away excess heat during intense activity. When zipped up, the high collar shields the neck from cold air and improves thermal protection in windy conditions or low temperatures.

The use of flat seams reduces the protrusion of fabric joins and lowers the risk of skin irritation. This is particularly important when wearing the sweatshirt directly against the body and during prolonged exertion.

The back of the sweatshirt is extended to better cover the lower back during movement. This design reduces the material riding up when leaning forward, bending down, and raising the arms.
