Abstract

Cette invention porte sur un gilet pare-balles conçu de manière à laisser un espace entre le gilet et le corps du porteur, de sorte que le gilet ne colle pas étroitement au corps du porteur, ce qui permet d'améliorer tant les qualités de protection que de ventilation du gilet. L'invention porte également sur un vêtement de séparation ainsi que sur une pièce supportée adaptée pour agrandir un gilet pare-balles existant, et ce dans le même but.
