The Inner:Dual Merino Long Sleeve is your technical base layer for demanding adventures and everyday challenges. The innovative double-layer knit construction combines a wool-polyamide blend on the outside with a soft polyester lining on the inside—a design that perfectly combines insulation, moisture management, and comfort. The functionality is well thought out: sweat is quickly transported from the soft inner layer to the outer wool layer, keeping you dry and comfortable. The additional loft of the two-layer construction enhances heat retention without unnecessary bulk. Merino wool brings its proven advantages: natural temperature regulation that balances you in cold and warm conditions, natural odor control for multi-day use, and a timeless, sustainable material. Whether you're out in the mountains or simply looking for a reliable base layer for winter, this long sleeve delivers unmatched performance and comfort you can rely on.
