Jacket for playing tennis in the rain

[Walkingtheplank]

DD, aged 14, needs a water repellent jacket for playing tennis in the rain. Obviously her preference is not to play in the rain but sometimes it happens to rain when she has her lesson.
She's looking for something she can move in, keeps her warm, but not too warm most importantly keeps her relatively dry.

She is a slim 5'7" so needs adult sizing.

I thought she could wear a running jacket but all the ones I've seen are well over £100 when I'd rather spend less than £50.

Any tips gratefully received,

Have you looked at Decathlon. This one is only £24.99.

I'm pretty sure I bought an even cheaper one from there but I can't see it on the website now.

That's quite nice. Thank you. I looked at the website at the weekend and didn't notice it. I'll show DD.

I have a running jacket from Asics, very light and waterproof. I occasionally use it for tennis too.
