Salewa Women's Alpine Merino Thermal Leggings XL Black Out

On a crisp alpine morning, when frost clings to the ridgeline and the air bites, the right base layer makes all the difference. The Salewa Women's Alpine Merino Thermal Leggings in size XL and Black Out are built for those who push into cold, high-altitude environments—whether skinning up a couloir, trekking through snow-dusted forests, or belaying on a north face. These tights combine the natural performance of merino wool with technical synthetic fibers, delivering warmth, breathability, and unrestricted movement in a sleek, athletic silhouette.

Why choose it

Merino wool is nature’s high-performance fiber—it regulates temperature, wicks moisture away from the skin, and stays fresh even after multiple days of wear. Blended with polyamide for durability and elastane for stretch, these leggings move with you on steep ascents and technical terrain. The flatlock seams eliminate irritation under a harness or pack, while the slim cut layers cleanly under shell pants or ski trousers. Salewa’s commitment to sustainability means you’re choosing a product made with responsible materials and processes.

Ideal use cases

• Alpine trekking and mountaineering in cold conditions
• Ski touring, backcountry skiing, and winter hiking
• Ice climbing and cold-weather belaying
• Everyday winter layering for outdoor work or commuting
• Multi-day trips where odor resistance matters

Good to know

These leggings are machine washable on a cold cycle; do not bleach, iron, or dry clean. Tumble dry on low heat. The Alpine Merino fabric is naturally breathable and quick-drying, so you stay comfortable during high-output activities. For a complete system, pair with a Salewa merino top and a windproof shell. Note: the colour Black Out is a deep, solid black that pairs easily with any outerwear.
