For its latest partnership, Under Armour has teamed up with French designer Marine Serre to create a capsule collection that brings together athletic innovation and the designer’s distinctive approach to contemporary dress.
The limited-edition collection marks the first collaboration between the two brands and arrives as Under Armour celebrates its 30th anniversary. Drawing inspiration from the American sportswear label’s early-2000s archive and its pioneering HeatGear® technology, the capsule reinterprets performance essentials through Marine Serre’s lens of precision, functionality and movement.
Under Armour was originally founded in 1996 in Baltimore by Kevin Plank, growing from a simple garage operation into a multi-billion-pound sports titan. “Whether in training or in design, progress comes from deliberate repetition and purposeful execution,” says Yuron White, SVP, GM of Sportswear and Collabs at Under Armour.

Sport has long inspired Serre’s work. Before establishing her eponymous label, the designer competed as a professional tennis player, an experience that continues to shape her understanding of clothing and the body. That connection forms the foundation of the collection, which centres on the baselayer – that is, the garment closest to the athlete.
For Under Armour, the baselayer remains the product that launched the brand nearly three decades ago. For Marine Serre, its counterpart is the house’s recognisable ‘Second Skin,’ often decorated with the label’s signature crescent moon motif. In this collaboration, those two identities merge through a series of fitted silhouettes crafted using Under Armour’s HeatGear® fabric technology.
The collection adopts a deliberately pared-back palette of black and white, emphasising streamlined cuts and technical construction. A newly developed graphic combines Marine Serre’s crescent moon with Under Armour’s heartbeat logo, creating a visual language that connects both brands while reinforcing themes of discipline, endurance and progress.

Alongside the apparel, the collaboration revives one of Under Armour’s lesser-known archive designs. The ‘UA Proto Speed II’ sneaker returns for the first time since the late 2000s, updated with layered textiles, sculptural leather panelling and exclusive co-branded detailing. While its original silhouette remains intact, the reworked design reflects the cleaner, more considered aesthetic that defines the wider capsule.
“Sport has always been part of my life,” says Serre. “With Under Armour, I wanted to explore the beauty of movement through pieces that combine performance, precision and beauty.”
To mark the release, Marine Serre and Under Armour will host a dedicated pop-up space in Paris from 5–7 June. Located on Rue de Turenne in the city’s Marais district, the installation has been designed to immerse visitors in the collaboration’s world, exploring the relationship between athletic performance, craftsmanship and contemporary design.

The collection launches today exclusively through Marine Serre channels online and at selected boutiques, before rolling out globally through Under Armour later this summer. Discover more here.
