color as the NHL shield. The Blackhawks wore this logo patch underneath the numbering on the right-sleeve on both the home and away jerseys. The Blackhawks debuted this patch on their home jerseys on January 5, 2017, and then they debuted the patch on the away jerseys on January 13, 2017. All home and away jerseys for all thirty teams will continue to have patches of the NHL's centennial emblem for the 2017–18 season, located above or below the numbers on their right sleeves, for at least up to the playing of the NHL 100 Classic on December 16, 2017. Adidas signed an agreement with the NHL to be the official outfitter of uniforms and licensed apparel for all teams, starting with the 2017–18 season, replacing Reebok. The Reebok Edge template will now be retired in favor of the Adidas' ADIZERO template. The home and away uniforms that were debuted in the 2007–08 season remain nearly identical with the exception of the new Adidas ADIZERO template and the new collar. With the new collar, the NHL shield remains but is no longer placed on a lower layer with flaps nearby, as it's now front and center on a pentagon with a new "Chrome Flex" style. The waist stripes are now curved instead of being straight across. The Adidas logo replaces the Reebok logo on the back collar. For the entire 2018–19 season, on both the home and away uniforms, the Blackhawks wore memorial patches in remembrance of Stan Mikita, who died on August 7, 2018. The memorial patch featured 21 in white on a black circle that is placed on the upper left corner on the front side of the uniform. For the 2019 NHL Winter Classic, the Blackhawks wore uniforms similar to what they wore from the 1926–27 season to the 1934–35 season. The black and white uniform features the black and white Native American head logo on a black and white roundel with the wording "Blackhawks" arched on top and "Chicago" arched below. The Native American head logo inside the roundel features the 1999–2000 native American head logo that they currently wear. The uniform has four white stripes on each of the shoulders, and five white stripes of varying thickness on each sleeve and around the waist. Inside the collar, we see several diagonal white lines, which is a nod to the end zone design used at Notre
