Style Crafted to Brave the Elements: All the Details on Jannik Sinner’s Custom Nike Look

On Nike’s part, the crafted ensemble is a statement on the athlete-brand partnership, a glimpse into how Nike approaches serving athletes with performance and expression on the world stage. The layered system for Sinner moves beyond simply a competition kit and reflects his Alpine roots and the life he leads when he’s not competing.

“For me, it’s very important to always have a small sign of where I’m from. Take the carabiner, with the mountain detail — the small details always make a very big difference,” he says. The reference is to a pure silver keychain carabiner hanging from a chain on the custom pant; the carabiner was created in a shape inspired by an elevation map of the Alps, where Sinner spent years skiing growing up.

Made to Sinner's exact specifications, the one-of-one look was created by Nike Senior Design Director Raffaella Barbey, working alongside Lotti, and a multidisciplinary design team. Barbey oversaw fittings with Sinner in Melbourne during the Australian Open, taking his input directly into production and refining the details through multiple rounds of iteration.

Early versions of the jacket featured orange piping, which designers ultimately softened after hearing his input, opting for a more muted palette aligned with his personal style. Together, the team focused on balancing Nike-only performance innovation with premium craftsmanship and elevated design.

The resulting layered system centers on a custom ACG vest featuring adaptive A.I.R. technology — the same innovation used in the Therma-FIT Air Milano medal-stand jackets worn by Team USA — paired with tailored outerwear and footwear built to perform in winter conditions without sacrificing style.

“This experience felt very different from work I’ve done with other brands,” Sinner says. “I was more involved in the process. There were a lot of conversations about what could be better, what wasn’t right, what worked well. In the end, we came out with an incredible result.”

For Lotti, projects like this reflect a broader approach to design, one shaped by decades of athlete partnerships, iconic products and culture-defining moments.

“When you’re designing something one-of-one like this, the process begins the same as it does when we’re creating for competition: by listening to the voice of the athlete. What their preferences are and what their needs are, both from a performance point of view and from a visual perspective,” Lotti says. 

“What’s different is that we can push the limits more — on innovation, on methods of make and on material choices. From a design point of view, we can also include bespoke and personal design details. And we can act much faster, working on a much shorter timeline because we’re only building one versus 500 or 10,000.”

In Sinner’s case, that meant creating something that reflects the person behind the ranking — an Italian athlete shaped by the mountains, with a clear point of view on style and a life beyond the court that has always informed how he moves through the world.

At Nike, projects like this aren’t treated as one-and-done statements. They’re part of a broader commitment to designing with athletes at defining points in their journey, built on long-term relationships, close collaboration and a shared investment in getting it right.

Lotti has a name for that approach: Nike Atelier.

A platform for creating custom designs for select signature athletes at key off-field moments, Atelier applies the same athlete-driven mindset and attention to craft that define Nike innovation, extending it into moments where identity, environment and culture play an equally important role.

“Sinner is one of the best tennis players in the world but what many people don’t know is that he was a championship skier growing up,” Lotti explains. “He was one of the top ski racers in Italy and a national champion in giant slalom. He also grew up not far from here in the Dolomites."

That gave Lotti and team the perfect ingredients for a Nike Atelier project: Sinner the skier, the games in his home country, the relaunch of ACG in Milan and Nike introducing A.I.R. apparel innovation with the Air Milano jacket. “The result is something unexpected yet completely authentic to both Sinner and Nike," says Lotti "Bespoke, ACG-inspired, one-of-one expression that sits at the intersection of sport and culture.”

Seen on Jannik in Milan last week, the element-proof, head-turning fit shows everything about that intent. A reminder that sometimes the most compelling design stories begin by paying attention — to the athlete and everything that exists beyond the scoreboard.

“When a brand invests this much thought and energy into a single moment, it shows they really care about making the athlete feel special. That’s one of the biggest reasons why I love being with Nike — they make you feel important," says Sinner. "You try to give positive feedback and grow together in the right direction. We’ve worked together for years now and feel close, like a family. That’s what matters to me.”
