A quail cloth is a utensil that is used in a sauna . This is usually a towel or bath towel that is swung in a circle during the infusion to move the hot air from above (the ceiling) down to the sauna guests.
For hygienic reasons, the towel is only intended for this purpose and is in no way used to lay it under or on it. The use of your own sweat towel for this purpose usually results in a sauna ban.
The expression "quail cloth" comes from the Austrian culture and is etymologically derived from wacheln , waving , fanning .
