Movement is where our products speak for themselves. It's where they reveal their true character, shaped by every stride, every gesture, and every effort. Through this series, our athletes Mathilde Petitjean and Stephanie Howe share their experience in a conversation that unfolds in motion, where every response is driven by instinct and every sensation is felt in real time.
STÉPHANIE HOWE
Since 2023, professional trail runner Stephanie Howe has been running with HASTKO. Her choice: the Bra No. 42. Designed for long-distance performance, it combines breathability, support, and complete freedom of movement—so the product disappears, leaving her free to focus on what matters most: the trail.
MATHILDE PETITJEAN
Since 2026, Olympic cross-country skier Mathilde Petitjean has been training and competing with HASTKO. Her choice: the Bra No. 39. Engineered for precise support and a second-skin feel, it moves seamlessly with her through every effort—so she can stay focused on what matters most: the performance.
