Designed for those who stay committed to their passion even as the cold sets in, this pack combines two winter essentials: the Endurance Base Layer and the Men in Tights Leggings—a duo that redefines comfort and performance in chilly conditions. The Endurance Base Layer is your go-to first layer. Lightweight and seamless, it fits like a second skin. With thumbholes to keep warmth in and a mesh back for optimal ventilation, it keeps you dry and comfortable, even during your most intense workouts. The Men in Tights Leggings are engineered for a supportive fit without compression or chafing, ensuring your legs stay warm and comfortable. The firm, stable waistband keeps them perfectly in place throughout your run, while the side pocket securely holds your essentials without compromising your freedom of movement. At €149 instead of €184, this duo equips you for winter with the perfect blend of comfort, warmth, and technical excellence.
