This cold-weather bundle pairs two running essentials engineered to deliver the perfect balance of warmth, comfort, and supportive coverage. The Endurance Soft base layer acts like a second skin: warm, featherlight, and completely chafe-free. The seamless tights adapt to every move and stay locked in place with an elastic-free, high-rise waistband—delivering a smooth, distraction-free stride from your first step to the final kilometer. • Seamless anti-chafing: seamless knit (top and leggings) to eliminate irritation and discomfort. • Warm and light: new, finer and more supple yarn. Same warmth, less weight (base layer). • Second-skin fit: optimal insulation and total freedom of movement. • Targeted protection (cold/wind): double-layer high collar and raglan sleeves. • Practical in winter: watch slit to check your data without letting the cold in. • Hold that doesn’t budge: high-waisted, elastic-free leggings with stable fit. • Sensitive-skin comfort: seamless material designed to limit chafing. • Ventilation and fit: knit details at the waist and on the legs. • Essentials secure: patch pocket at the back of the leggings. At 144€ instead of 184€, this duo lets you equip yourself with the best in comfort and performance.
