Jockey International is extending its partnership with NASCAR Cup Series team Trackhouse Racing.
The apparel brand, which celebrates its 150th Anniversary in 2026, first partnered with the Justin Marks-led operation in 2022 and has continued to outfit Trackhouse employees with wearables for the season since then.
This season, the Kenosha, Wisconsin-based brand will serve as a primary sponsor for Ross Chastain (No. 1) and NASCAR Cup Series rookie Connor Zilisch (No. 88).
“We are pumped to be back with Trackhouse Racing for the 2026 season as we celebrate our 150th anniversary,” said Matthew Waller, director of PR & partnerships, Jockey. “This is a collaborative relationship driven by performance, innovation, and purpose – qualities that brought our two brands together in 2022. The outlook on this season is very promising for Trackhouse, and we are excited to see both Ross and Connor drive their Jockey Chevrolet to victory lane.”
Last season, as a major highlight of the relationship between Jockey and Trackhouse Racing, Ross Chastain was able to bring his No. 1 Jockey International Chevrolet to Victory Lane in the Coca-Cola 600 — a feat he managed to pull off after starting in last-place.
“It was fun to get Jockey into Victory Lane last year at Charlotte,” said Chastain. “They’ve been on my car for several years, and I’m excited to work with them again this year as they celebrate 150 years. I’m looking forward to the exciting things they have planned for this season. I have no idea what they are going to ask me, or my pit crew, to wear next.”
Zilisch, a rookie in the NASCAR Cup Series this season, will wheel a Jockey-sponsored Chevrolet for the first time at Las Vegas Motor Speedway on March 15, in a racecar decked out to celebrate the brand’s 150th Anniversary.

“I’m looking forward to driving the Jockey 150 anniversary car in Las Vegas,” said 19-year-old Zilisch. “I’ve seen some of the campaigns Jockey has worked on with Ross, Justin, and the pit crew guys in their underwear, which are pretty funny. This is a big year in my career, and I’m thankful to have the support from a well-known brand like Jockey.”
Ross Chastain will run his first race of the 2026 NASCAR Cup Series campaign with Jockey International on-board his No. 1 Chevrolet at Talladega Superspeedway on April 26.
Since the partnership between Jockey International and Trackhouse Racing began in 2022, the underwear brand has appeared on one of the team’s Chevrolet entries in the NASCAR Cup Series a total of 32 times, netting a total of eight top-five finishes, and only one victory — the 2025 Coca-Cola 600.
The NASCAR Cup Series event at Las Vegas is scheduled for Sunday, March 15.
