What do the t-shirts mean?

I’d really like to know why a coloured T-shirt sometimes appears next to someone’s name on zwift (right of screen) - are they in a race / race winnner?

It looked like zwift we’re doing some sort of testing at the weekend (green top) - playing with steering probably.

Often I’ve seen red/white t shirt colours pop up and figured they’d just won a race?

Hi @Ewan_McDonald

Those are for Sprint, KOM and Lap segments. If you are the fastest in a sprint segment you will get the green jersey and you will have it for one hour or until someone goes faster.

See this.
