This long-sleeve thermal shirt is a versatile base layer designed to provide comfort across a wide range of outdoor activities throughout the year. Made from 100% merino wool with a 200 g/m² fabric weight, it combines softness, breathability, and effective temperature regulation.

The natural properties of merino wool help maintain a comfortable body temperature by retaining warmth in cold conditions and supporting cooling during increased activity. The fabric is naturally odor-resistant, making the shirt suitable for extended hikes, travel, and multi-day adventures.

The construction features underarm gussets for improved mobility and comfort. Offset shoulder seams help reduce friction when carrying a backpack, while flatlock seams minimize chafing against the skin. The drop-tail hem provides additional coverage during movement.

Its slim fit allows comfortable layering beneath a fleece, insulated jacket, or waterproof shell without adding unnecessary bulk. The shirt is suitable for hiking, trekking, skiing, winter sports, and everyday wear in cooler conditions.
