Such pestemals are traditionally used in Turkish bathhouses, where they are available to men as loincloths and to women as body coverings.
You can also use the hammam towel on the beach, at the lakeside or at the swimming pool, because the special treatment makes it dry particularly quickly.
Wash tip: up to 30 degrees. Please don't use fabric softener, do not spin. Make shure to dry at low temperatures and wash separately before first use.
