There have been a small number of instances recently where the wearing of a two-piece female race suit has been challenged.
The suit in question is the Arena Powerskin Carbon duo, which consists of a jammer style leg suit with a bodysuit over the top and can be viewed at https://www.arenasport.com/en_uk/powerskin-carbon-duo
This suit was launched in 2019 but obviously due to the limited number of competitions seen in 2020 and 2021, there have not been many opportunities for it to be seen in action.
For the avoidance of doubt, this is a FINA approved suit and bears the FINA approval logo on both parts. Swimmers wearing this suit with the logo on both parts for competition should not be challenged.
