100% seamless sports bra - Women -
Available colours:
Discover the revolutionary Bra n°42 Ardoise from the French brand Hastko, representing the perfect blend of technical innovation and feminine elegance, designed to protect against any irritation. This is notably the brand’s model best suited for running.
This model, the result of meticulous design created by women for women, embodies the perfect harmony of performance, comfort and femininity, allowing you to push your limits with confidence and style.
Its 100% seamless construction, achieved through thermo-welded assembly, ensures unmatched comfort and drastically reduces irritation, even during the most intense and prolonged efforts. The wide laminated underbust band provides optimal support, gently framing the bust without ever compressing it, while the absence of underwires guarantees total freedom of movement. Made from a breathable, quick-drying fabric, it effectively wicks moisture away, keeping you dry and comfortable. The thin removable cups allow for personalised support adjustment, and the ultra-flat straps discreetly blend under all your clothing.
The secret to its second skin effect lies in an innovative 3D printing process that delivers an exceptional softness. Ideal for performance sports and long efforts, this bra slips on without adjustment, for maximum ease of use.
Developed in the heart of the Alps, it embodies excellence and ingenuity.
