Nike Flight Hi-Vis is the official winter ball of the Premier League 2020-2021. In a technological sense, this ball does not differ from the base model of the Premier League 2020-2021. However, in traditional winter colors, these grooves tinted red in a waning gradient, look particularly cool.
The stylistic model of Nike winter balls was developed in 2005 and has not changed since then. English fans are pretty conservative in a good way and appreciate tradition. This is why Nike winter balls are so popular every season.
