The S1 is designed for a large-area long rifle protection and offers high wearer comfort. Additional plates in the abdomen and throat area complete the classical protection concept. The most important organs of the upper body as well as the large arteries in the neck, torso and leg areas are covered extensively. All functional elements are simplified to the maximum and can be understood easily and instinctively by the user. The vest is equipped with patented "Hakenschnalle" fastenings in the shoulder and flank area, which allow very fast donning and doffing.
