*The All Japan Kendo Federation recommended the use of a Tenugui or similar kind of mask inside your Men for regular practice (and competitions in Pandemic times), but not normal mask (not for sports, not good breathability) since they can lead to Heatstrokes, and if you have problems to breathe they suggested that you could use it below your nose. for this reason, if you want to strengthens this protection but still be able to breathe we think these shields may help you, but it is not recommended to use only the shields alone.
