All about Men's Merino Xtreme Thermal Shirt (80% Merino)
Merino Xtreme is Thermowave's most popular collection, designed to impress you with its comfort, functionality, and durability. The Thermowave Merino Xtreme thermal shirt for men features a dual-layer construction: merino wool and polyamide as the outer layer retain heat, allow the skin to breathe, and prevent unpleasant odors, while polyester as the inner layer absorbs moisture and allows it to evaporate quickly, even in the coldest conditions and regardless of your activity level.
These ultra-soft, skin-friendly products provide your body with comfort, dryness, and warmth, even during the most unexpected adventures.

MerinoDry Technology
MerinoDry technology ensures you feel fresh, dry, and warm for longer. We have developed a double layer with functional polyester on the inside and natural merino wool on the outside, which provides better breathability and extra warmth. Functional polyester quickly wicks away excess moisture, and merino wool is known not only for its warmth but also for its natural antibacterial properties that protect against bad odors.
Sustainability
Merino wool acts like a personal climate control system for the body, maintaining a stable temperature: it keeps the body cool when it's hot and warm when it's cold. It is eco-friendly because merino comes from the best that nature has to offer - water, fresh air, sunlight, and grass. Merino wool grows back annually, is 100% biodegradable, and always delivers the best performance. Forget unnecessary moisture, dampness, and itching, as this is the softest and most breathable clothing you will ever find. Every Thermowave garment is made from mulesing-free merino wool. We are very proud of this decision and know that the welfare of the sheep improves as more and more manufacturers follow this path. We have a saying that happy sheep don't itch, and we stand by it. Recycled polyester is the ideal sustainable choice - recycled fabrics require fewer resources while retaining the excellent properties of the fiber. Recycled polyester ensures lasting comfort and minimal thickness, offers exceptional moisture-wicking, and moves freely with you, even during the most demanding activities.
