This equipment is called Bogu. It is the training armor used primarily in the Japanese martial art of kendo.
I have 2 sets of face guard, chest protector, glove and groin protector.
men (面): combined face mask and shoulder protectors (helmet); size 68 cm
kote (小手): hand and forearm protectors (gauntlets); size large but this is more like an American small
dō (胴): torso protector (breastplate); size medium
tare (垂れ): groin and leg protectors (faulds). size medium
These are brand new in perfect shape.
Purchased from E-Bogu.com
