Nylon and neoprene jacked weighted with gel. Born thinking of use during games; soccer, basketball etc. Weight 5 kg, compact size, but not too small, to distribute weight and increase grip, on the body. Wrappy and elastic structure, because of this the jacket stays blocked on the torso, even during the contact phases between athletes.

The ballast are made with soft sachets, filled with weighted gel; again to prevent dangerous object inside the vest. See also Code 1794 Weighted Jacket KG 15.
