Indonesia Home Shirt 2020/21 (S) is a red home kit produced by Mills for the Indonesia national team during the 2020/21 international period. This Indonesia shirt arrived as Shin Tae-yong began his tenure as head coach, with the national side focusing on training camps and unofficial friendlies after COVID-19 forced the postponement of their 2022 World Cup qualifying matches. The squad later reached the final of the delayed 2020 AFF Championship in late 2021.

The design features a red base with a tonal geometric camo pattern across the fabric, combined with gold detailing for the national crest and manufacturer branding. A short sleeve cut and v-neck collar keep the look clean, while the absence of a sponsor reflects the typical national team presentation. Pieces from this era are increasingly sought after by collectors of the Indonesia vintage shirt scene and those looking for an authentic Indonesia football shirt or Mills Indonesia jersey.
