Ukraine's EURO 2020 shirt has sparked outrage in Russia due to its controversial design.
The new home jersey was released on Sunday ahead of the tournament and shows a map of the country's borders including the Crimea peninsula.
Russia annexed the region in 2014 and considers the peninsula part of its territory, something which is not internationally recognised.
The Yellow and Blue's new strip is emblazoned with both the outlined map and slogans, such as "Glory to Ukraine" on the back of the neck.
Inside the shirt, text reads "Glory to the heroes."
The phrases were chanted when protesters ousted a pro-Moscow president in 2014 and are now staples of patriotism in the nation as well as military greetings.
Russian MP Dmitry Svishchev described the shirt as "totally inappropriate," and foreign ministry spokeswoman Maria Zakharova claims Joma's product gives an "illusion of the impossible."
Svishchev, a parliamentary deputy, was also quoted by news agency RIA as saying the shirt was "a political provocation" and any map of Ukraine containing "Russian territory is illegal."
Zakharova cited on social media that the jersey expressed nationalistic sentiment and the slogans echoed a German Nazi rallying cry.
The annexation of Crimea severely damaged relations between Moscow and Kyiv in 2014 and marked the start of a Russian-backed separatist rebellion in eastern Ukraine.
The outlined map also shows the pro-Russian separatist-controlled areas of Donetsk and Lugansk.
Andriy Pavelko, head of the Ukrainian football association, shared this promotional video on Facebook in which the borders are even highlighted in one shot.
"We believe that Ukraine's silhouette will give strength to the players because they will fight for all of Ukraine," Pavelko explained.
Former Chelsea striker and ex-Ukrainian politician Andriy Shevchenko now manages the Yellow and Blues, who start their EURO 2020 campaign this Sunday against the Netherlands in Amsterdam.
Shevchenko entered politics after retiring in 2012 and the 2004 Ballon d'Or winner has been in charge of his national team for the last five years.
The teams are joined in Group C by Austria and European Championship debutants North Macedonia.
Can Ukraine put this controversy behind them to be dark horses at EURO 2020? Comment below.
With the tournament taking place across 11 major cities, Ukraine could travel to St Petersburg at some point.
The city, which replaced Dublin as a host, boasts one quarter-final along with games in Group B and E.
Shevchenko's side could play in Russia if they were to finish third in their group and follow the relevant pathway.
UEFA will be hoping tensions ease if that becomes the case, usually ensuring ideologically opposed nations (such as Serbia and Kosovo) avoid playing each other in qualifying.
Ukraine lost all three of their matches at EURO 2016, failing to score in any of them.
In 2012, their home advantage was futile as they, alongside Sweden, fell in a group containing England and France.
Having failed to reach the 2018 World Cup in Russia, the Yellow and Blues' qualification for this delayed tournament was a success, topping a group containing holders Portugal whilst going undefeated.
Ukraine's hopes for this summer lay on the likes of Manchester City defender Oleksandr Zinchenko and West Ham United forward Andriy Yarmolenko, as well as one to watch Ruslan Malinovskyi, who shone for Atalanta in Serie A this season, racking up eight goals and 12 assists.
