Dame Stadium. Mixed in between these white lines are the six years written in red, the six years the Blackhawks won the Stanley Cup. The Blackhawks won the Stanley Cup in 1934, 1938, 1961, 2010, 2013, and 2015. After the 2019 NHL Winter Classic, the team announced that uniforms from the game would be worn in three home games of the 2018–19 season. For the 2019–20 NHL season, the home and away uniforms that were unveiled for the 2017–18 season remain nearly identical with the exception of the new collar designs. The new collar on the home uniform transitions from white to a solid red on the front as it comes over the shoulder, leading into the NHL logo with a red background in the center. The new collar on the away uniform transitions from red to a solid white on the front as it comes over the shoulder, leading into the NHL logo with a white background in the center. Beginning with the 2020–21 NHL season, the league allowed for advertising on its gameday uniforms for the first time, starting with helmet ads. The Blackhawks' first helmet ad sponsor was United Airlines. For the 2020–21 NHL season, the Blackhawks would wear "Reverse Retro" alternate uniforms. The design was largely inspired from the team's 1940s uniforms minus the barber-pole elements. A second "Reverse Retro" uniform was released in the 2022–23 season, based on their 1938 uniform. Across the chest is "CHICAGO" in white with red trim, inspired by the 2019 NHL Winter Classic crest and the current Blackhawks primary logo is added as a shoulder patch on the left side. Starting with the 2021-22 NHL regular season, Adidas introduced new environmentally-friendly uniforms for all teams with its Adidas ADIZERO Primegreen Authentic template. The template is made with a minimum of 50% recycled content while still retaining their high-performance materials. Each team uniform will maintain its classic stripping and logo, while boasting dimensional embroidery that draws attention to their sustainable materials, and a two-layer twill that underscores the product's authenticity. For the Blackhawks, the logo on their uniforms now feature raised markings on the face of their logo, the forehead lines, the eyebrow and eye, as well as the facepaint are all now raised rather than flat as it had been before. For the entire 2021–22 NHL season, on both the home and away uniforms, the Blackhawks are wearing memorial patches
