Marine Serre and Under Armour Introduce a New Vision of Performance

As Under Armour celebrates 30 years of redefining athletic performance, the brand enters a new chapter with French fashion house Marine Serre. In a debut capsule collection, Marine — inspired by Under Armour’s iconic 2000s sportswear archive and its most famous innovation, the baselayer — reframes sports as a universal language of the body.

The limited-edition capsule launches June 5 exclusively on marineserre.com , at select Marine Serre retail locations, and through an immersive pop-up experience in Paris running June 5–7, before expanding globally later this summer on UA.com . Located at Rue de Turenne, 75003, the pop up will feature an environment that brings the collection into dialogue with space — where the raw energy of sport meets the refinement of craftsmanship and art, inviting visitors into the world of Marine Serre x Under Armour.

Through Fashion Marine Serre has become one of fashion’s most influential modern houses by dismantling traditional systems of dress and reconstructing established codes into something entirely new. Drawing on her own experience as a former professional tennis player, Marine approaches design with the instincts of both maison and athlete, bringing rigor, restraint, and clarity to the way movement is shaped through fashion.

That shared ethos made the baselayer the natural foundation of the Under Armour x Marine Serre capsule — and a blank canvas for exploration. Long valued for function alone, the garment worn closest to the body is reimagined through Marine’s lens as something destined for more. It becomes a symbol of origin: where movement begins, where discipline is built, and where performance is remembered — for every body, across sport and street.

"With Under Armour, I wanted to explore the beauty of movement through pieces that combine performance, precision, and beauty — starting from the baselayer, the closest element to the body and to the athlete’s experience”

Where Performance Begins

The baselayer is at the heart of both brands’ origins. For Under Armour, it is the product that started it all: engineered to endure, refined through decades of athlete insight, and trusted across every sport and condition. For Marine Serre, it is the House’s iconic “Second Skin”: the Moon-patterned layer that is the emblem of its creative identity. Together, these foundationsconverge in a collection shaped by intention, elegance, and respect for movement and the body in all its forms.

The design language of the debut capsule is stripped back and deliberate. lean lines and sharp contrasts of black and white, crafted with Under Armour’s HeatGear®, reflect the focus and intensity of sport at its highest level. A bespoke print merges Marine Serre’s signature Moon with Under Armour’s heartbeat logo, bringing together two symbols grounded in discipline and belief in progress.

The UA Proto Speed II also emerges from the archives for the first time since the late 2000s. A layered textile base, sculptural leather paneling, and silicone Under Armour x Marine Serre logo on the toe and vamp of the shoe preserve its nostalgic DNA while reimagining it through a modern lens.

“Whether in training or in design, progress comes from deliberate repetition and purposeful execution. Beginning with the baselayer felt instinctive. It’s where that process exists closest to the body — and where our two perspectives meet with clarity and authenticity.”
