The clothing which is worn in modern fencing is made of tough cotton or nylon.The complete fencing kit includes the following items of clothing:
Form-fitting jacket covering groin and with strap (croissard) which goes between the legs, a small gorget of folded fabric is also sewn in around the collar to prevent a blade from slipping upwards towards the neck.
Under-arm protector (plastron) which goes underneath the jacket and provides double protection on the sword arm side and upper arm. It is required to not have a seam in the armpit, which would line up with the jacket seam and provide a weak spot.
One glove for the sword arm with a gauntlet that prevents blades from going up the sleeve and causing injury, as well as protecting the hand and providing a good grip
Breeches or knickers which are a pair of short trousers. The legs are supposed to hold just below the knee.
Knee-length or Thigh high socks which should cover knee and thighs.
Shoes with flat soles and reinforcement on the inside of the back foot and heel of front foot, to prevent wear from lunging.
Mask, including a bib which protects the neck. For competition, the bib must be sewn into the mask frame to eliminate a hole that might admit a blade. Thus, masks with snap-in bibs are not legal for competition. The mask can usually support 12 kilograms of force, however FIE regulation masks can stand much more, at least 27 kg.
