This men's thermal top is designed as a heavyweight base layer for the coldest days and demanding winter activities. Made from 100% merino wool with ultra-fine 15.5-micron fibers, it delivers exceptional next-to-skin softness, reliable warmth, and natural temperature regulation.

Merino wool helps maintain a comfortable body temperature, manages moisture, and naturally resists odors. These properties make the thermal top suitable for extended wear during skiing, snowboarding, winter hiking, and multi-day outdoor adventures.

The half-zip allows easy ventilation adjustment according to activity level and weather conditions. Thumb loops keep the sleeves in place and provide additional hand coverage. Flatlock seams help reduce friction, while the drop-tail hem offers improved coverage during movement. A zipper chin guard prevents uncomfortable rubbing around the chin.

The slim fit allows comfortable layering beneath a fleece, insulated jacket, or waterproof shell without unnecessary bulk. This thermal top is an excellent choice for winter sports and outdoor activities in cold climates.
