Ballistic neck protection – K2 ‘Sprężyk’
"Łasica" – Plate Carrier Multicam
lub
„Gronostaj”
The ASTRIVA ballistic protective collar has been designed as an additional module to increase the area of protection for the wearer around the neck, shoulders and upper back – areas that a standard body armour vest or plate carrier does not usually cover.
The set comprises a front collar section attached to the vest via a MOLLE system and a split rear collar. This design allows for freedom of movement of the head and neck, whilst increasing the area of protection around the nape of the neck, shoulders and upper back.
The outer fabric is made from durable 770 dtex ‘TAKTYK’ FC IRR FR CORDURA® and a Cordura-based laminate. The materials used have IRR properties, which reduce the visibility of the equipment under night vision.
The collar is sold complete with soft ASTRIVA K2 ‘Sprężyk’ ballistic inserts. These inserts provide protection against, amongst other things, the 7.62 × 25 mm TT round, as confirmed by comprehensive ballistic tests carried out at the Military Institute of Armament Technology (WITU). The flexible design of the K2 “Sprężyk” inserts ensures both high comfort and adequate mobility.
Available colour variants include Multicam, wz. 93, Ranger Green and black.

Gwarancja Niezawodności: Proces Badań Balistycznych "Biegacz" K2
Quality that protects life
Our covers K2 “Biegacz” with Successfully passed all the tests, meeting the criteria standards PN-V- 87000:2011 and demonstrating a high level of reliability even under extreme conditions of use. Plate deflection was located in the compartment 26—31 mm, which remains below the permissible limit of 45 mm specified in the current standard.
This kind of comprehensive examination is crucial for us — not only as a formal requirement, but as proof of the quality and durability of a product that can decide human life in real conditions.
How do we test K2 ballistic cartridge?
Learn the detailed process of verifying the ballistic parameters of the “Runner” model. From strict legal requirements, to climate tests, to an independent expert assessment of each shot.
Compliance with Standard PN-V- 87000:2011
Before our product reaches the market, it must undergo rigorous ballistic tests, in accordance with the requirements of the Polish standard MON-V- 87000:2011. This standard specifies the test procedures for ballistic shields, classifying them according to their level of protection, and describes in detail the conditions that must be met during testing in order for the results to be reliable and comparable. These tests shall include ballistic resistance tests on a randomly selected group of shields from a given production batch.
Climate and Humidity Testing
Plates K2 “Biegacz” passed 4 series of rigorous trials in an accredited Laboratory of Research of Small Arms and Security Guards WITU. Each test was carried out on independent sets of plates under the conditions of:
Dry conditions — reference samples.
Irrigation simulation — assessment of the effect of moisture on the composite.
Heat up (+50°C) — Imitation of a hot climate.
Cool down (-40°C) — mapping Arctic conditions.
Impact Parameter Control
Each of the tests included 6 shots in precisely defined places on the board, according to the arrangement indicated in the standard, which allows to evaluate both the point resistance and the structural behavior of the shield after repeated firing. The key parameter was the preservation of a strictly defined projectile speed — in the case of the K2 class: 420 ± 15 m/s — with a shot distance of exactly 5 meters.
Methodology and Expert Supervision
A total of 48 shots (7.62x25mm P-shell ammunition) were fired during the tests under controlled test conditions. Each trial was evaluated independently by 2 experts conducting research. The evaluation took into account measurements of the velocity of the projectile and the subsurface depression under the cover formed as a result of the deformation of the plate.
