Men’s Thermal Long Sleeve Shirt Black

This men’s thermal long sleeve shirt is made from a high-performance merino wool blend (55% merino wool, 45% polyester), designed specifically to function as thermal underwear for cold and changing conditions.

Merino wool is naturally insulating and temperature-regulating, helping the body stay warm without overheating. It absorbs moisture vapor from the skin and maintains warmth even when slightly damp. Polyester enhances the fabric’s performance by actively moving moisture away from the body, allowing the garment to dry faster, retain its shape and remain comfortable during prolonged wear.

This combination creates an effective thermal layer that supports the body’s natural temperature balance. When the body warms up or perspires, moisture is dispersed through the fabric instead of staying against the skin, helping prevent chill and discomfort. As a result, the garment keeps you warm when inactive and dry when active — a key characteristic of true thermal underwear.

The lightweight structure makes it ideal as a base layer, while the slim men’s fit follows the body without restricting movement. Soft, smooth and non-itchy, the fabric is suitable for daily wear and extended use.

Perfect for everyday wear, work, travel, outdoor activities and winter layering.
