Where to buy a 100% cotton towelling long-sleeved beach poncho?

[Apologynotaccepted]

Can you help me find the following :
A 100% cotton towelling long sleeved beach poncho.
For boring reasons , I need to get in my car wearing it over my swimming costume, drive to the pool, swim, put it back on and drive home.
I've googled and found lots then they turn out to be microfiber, or short sleeved, or not long enough. Has anyone got what I need and can tell me where yoy got it from? Thanks in advance!

No thanks, I hate it!

Dry robe does towelling ones - i struggled finding them too as microfiber gives me the creeps

Wild moose

Years ago I had one from Toast. Probably early 00, although I know they did similar in linen more recently. It had pockets. It was incredibly heavy and was I think called a djellaba? If I find one on eBay or Vinted I’ll come back and link it.

Try Decathlon

I’ve had two from Amazon: one thick towelling one and a microfibre one. Both quite cheap.
