They’re also called peshtemals and it’s what I personally use exclusively. I don’t really care for big, fluffy towels, it feels like I’m drying off with a stuffed animal 
But in the US they are the norm so I give my guests a few big fluffy towels along with a couple of peshtemals and let them choose. Not everyone cares for them, including my husband, but the people who do are really appreciative of having them.
I get mine directly from a woman in Turkey on Etsy and they’re not particularly expensive. I sent you a link to it.
