Special edition home shirt released as part of a collaboration between Thai top-division side Buriram United and Leicester City, promoting the "Thailand Smiles With You" initiative that hopes to encourage the development of Thai footballing talent as well as providing support for those suffering as a result of the COVID-19 pandemic. Proceeds from shirt sales were funnelled towards the purchasing of 20,000 footballs for use by football groups and youth teams throughout Thailand. The unique design blends the navy of Buriram with the blue of Leicester, with an outline of Thailand to the reverse, in addition to featuring the crests of both clubs. It was worn in-game just once, in a fixture with Rayong F.C, as the Thunder Castle would go on to finish fifth in the Thai League 1
