Designed for winter trail running, high-altitude adventures, and outdoor training, these leggings feature Outopia’s exclusive 240GSM double-layer merino wool fabric for the perfect balance of warmth, breathability, odor resistance, and moisture management.

The innovative nylon inner layer + merino wool outer layer creates an advanced moisture-transfer system: sweat is quickly absorbed by the skin-friendly nylon fibers and transported outward. Soft like butter, four-way stretch, durable support. Wear it solo in spring and fall, or layer it effortlessly for winter training.

Smart waistband storage system lets your essentials stay secure and your hands are free. Using a women’s athletic fit, the silhouette follows your natural curves and creates a streamlined look for every woman.
