This men's long-sleeve thermal shirt is a versatile base layer designed for comfort across a wide range of outdoor activities throughout the year. Made from 100% merino wool with a fabric weight of 200 g/m², it offers an excellent balance of warmth, breathability, and softness.

The natural properties of merino wool help regulate body temperature by retaining warmth in cold conditions while maintaining comfort during physical activity. The fabric is naturally odor-resistant, making the shirt suitable for extended hikes, travel, and multi-day adventures.

Underarm gussets provide enhanced mobility, while offset shoulder seams help reduce friction when carrying a backpack. Flatlock seams improve comfort during extended wear, and the drop-tail hem provides additional coverage during movement.

The slim fit allows comfortable layering beneath a fleece, insulated jacket, or waterproof shell without adding unnecessary bulk. This versatile base layer is ideal for skiing, snowboarding, hiking, trekking, and other outdoor activities, as well as everyday wear in cold weather.
