swim cap that keeps hair dry

[LachrymoseLeeches]

Not sure if this really belongs in S&B but..

Can anyone recommend a swim hat that will actually keep your hair dry underneath?

Thanks

As a frequent swimmer, I don't think such a thing exists

Nor do I. I think caps are a) to make you more streamlined in the water and b) to protect the water from your hair

I use a Speedo long hair one that’s not bad- it gets damp around the edges but that’s all.

Thanks all. I recently saw a woman take off her swim cap and her hair was totally dry underneath. Unfortunately I didn't have the sense to ask her where it was from!

Mine does exactly this. A long hair one from Decathlon. I have long hair and wear it in a high bun underneath. X
