Carlos Sainz Merchandise 2026: The No. 55 Buying Guide as Williams Switches to New Era
Searching for "Sainz merchandise" in 2026 turns up more change than his number suggests. Williams re-signed its driver, but re-tooled almost everything around him — a new teamwear supplier and a sponsor swap that's actually rooted in Sainz's own career, not the team's. Here's what's official, what's actually different, and where to find each type of Sainz-branded product.
Carlos Sainz enters his second full season at Williams having done exactly what he set out to do after his surprise Ferrari exit — outscore expectations, grab a podium, and help drag the team back up the constructors' table. The gear around him changed more than he did: a new kit supplier, and a sponsor whose Williams arrival is really an extension of his own career-long backing.
Sainz Merchandise by the Numbers
- No. 55, unchanged: Sainz has raced with No. 55 since his Toro Rosso debut and keeps it through Renault, McLaren, Ferrari and now Williams — no switch like several of his fellow drivers made for 2026.
- 64 points, first Williams season: Sainz closed 2025 with 64 championship points, nine behind teammate Alex Albon, but scored 48 of those points in the final eight races alone (Albon managed just three in the same stretch), per Motorsport.com and RacingNews365's season recaps.
- Puma to New Era: Williams switched its official teamwear supplier from Puma to New Era for 2026 — New Era's first-ever Formula 1 team partnership — covering the race team, drivers, Williams Driver Academy, Sim Racing and Williams Heritage lines, per New Era and Williams' own announcements.
- Estrella Galicia 0,0 replaces Santander: Sainz's personal sponsor since his 2013 junior-racing days now backs the whole Williams team, appearing on the car's halo and rear wing endplate and on both drivers' helmets and race suits, with extra placements on Sainz's own helmet, per PlanetF1.
What's Actually Official Right Now
1. New Era x Williams Team Kit (2026)
This is the official race-team merchandise, made by New Era under Williams' first-ever kit deal with the headwear brand, sold through Neweracap.eu, Williamsf1.com and select retailers. Sainz's caps, polos and outerwear carry his No. 55 in Williams blue on a New Era cut rather than the outgoing Puma one. Search current Sainz Williams-style caps on Amazon for lower-priced licensed and fan-made alternatives to a full team-store purchase.
2. Why the Sponsor Branding Changed (and Why It's Personal)
Williams ended its one-season Santander partnership after the Spanish bank — which had sponsored Sainz at Ferrari and followed him to Williams for 2024 — decided to shift its F1 spending toward individual race sponsorships rather than a full team deal. Stepping in is Estrella Galicia 0,0, a non-alcoholic Spanish beer brand that has personally backed Sainz since 2013, through Toro Rosso, Renault, McLaren and Ferrari. Its new Williams deal effectively formalises that long personal relationship into a team-level partnership, with car and helmet branding for both Sainz and Alex Albon, plus extra placements reserved for Sainz's own helmet.
3. Everyday & Collector Items Featuring His Number or Likeness
Beyond official team kit, most day-to-day Sainz merchandise fans buy is generic F1 product tied to his number, team or driver likeness rather than a licensed capsule piece — and this is where our category guides come in.

How to Avoid Buying the Wrong Sainz Gear
Check the Branding, Not Just the Number
Because Sainz's number hasn't changed across Toro Rosso, Renault, McLaren, Ferrari and Williams, an old listing can still look current at a glance — the giveaway is the team livery and manufacturer branding, not the number. Confirm you're looking at Williams-blue, New Era-made 2026 stock if that's specifically what you want.
Know Which Team Era You're Buying
Unlike a driver who has stayed with one team his whole career, Sainz product spans four different liveries: Toro Rosso, Renault, McLaren, Ferrari and now Williams. That makes his merchandise more fragmented to shop than most — decide up front whether you want current Williams gear, his best-known Ferrari years, or an earlier chapter.
Decide If You Want Puma-Era or New Era-Era Williams Product
Both are legitimate purchases depending on what you're after: Puma-era pieces capture his debut and podium-scoring first full Williams season (2024-2025), while New Era product is what Williams is actually producing for 2026 and beyond, alongside the new Estrella Galicia 0,0 sponsor branding. Neither is "wrong" — just be clear on which one you're buying before checking out.
Frequently Asked Questions
What car number does Carlos Sainz use in 2026?
Carlos Sainz races with No. 55 in 2026, the number he has used since his Toro Rosso days and carried through Renault, McLaren, Ferrari and now Williams — it is unchanged going into his second full season with the team.
What kit does Williams wear in 2026?
Williams switched its official teamwear supplier from Puma to New Era for 2026, the first time New Era has supplied any Formula 1 team. The debut collection covers the race team, drivers, Williams Driver Academy, Sim Racing and Williams Heritage, sold via Neweracap.eu, Williamsf1.com and select retailers, per New Era and Williams' own announcements.
Why did Carlos Sainz's sponsor change for 2026?
Williams ended its one-season partnership with Santander, the bank that had sponsored Sainz at Ferrari and followed him to Williams in 2024, as Santander shifted its F1 spending toward race-level rather than team-level sponsorship. Replacing it is Estrella Galicia 0,0, a non-alcoholic Spanish beer brand that has personally backed Sainz since his 2013 junior-racing days — the brand's Williams deal effectively expands his long-standing personal sponsorship into a full team partnership, with branding on the car's halo and rear wing endplate and on the helmets and race suits of both Sainz and teammate Alex Albon, though Sainz gets additional placements on his own helmet.
How did Carlos Sainz perform in his first full season at Williams?
Sainz finished 2025 with 64 championship points, nine behind teammate Alex Albon's tally, but the season split into two halves: Albon led early with three points finishes in the first seven races, then Sainz took over, scoring 48 of his 64 points across the final eight races while Albon managed just three. Sainz also delivered Williams' only 2025 podium, a third place in Azerbaijan, and out-qualified Albon 14-9 across the year. His form helped Williams to fifth in the constructors' championship, the team's best finish since 2017.
Is Carlos Sainz's merchandise different from his Ferrari-era gear?
Yes. Any Sainz product still branded Ferrari or featuring Puma-era Williams kit (2024-2025) is now career-era gear rather than current stock. Current 2026 Williams product carries New Era branding, and team-level items may also carry the new Estrella Galicia 0,0 sponsor branding that Puma-era gear didn't have.
The Bottom Line
Sainz's 2026 story is proof his Ferrari exit wasn't the setback it looked like — a podium, a strong closing stretch, and Williams' best finish since 2017, now backed by his own long-time sponsor and a fresh kit supplier.
