You can do everything from Kendo warm-ups, suburi (practice swings), sparring with a men (helmet) on, to the final bow with just this one mask. It is made of jersey fabric, which is highly absorbent and quick-drying, and is often used for sportswear. The mesh side is sewn on the inside. This prevents it from sticking to your skin even when you sweat, and also makes breathing easier. The elastic bands will be sent untied. Please tie them to fit the wearer's face. Width at the top: approx. 18 cm Length: approx. 16 cm Children's sizes are also available. #Kendo #MenMask #SpitPrevention #Mask #KendoAccessories #KendoGoods #KendoSupplies
