CEST® Armor Ultra Pro Shirt ballistic undershirt short stab & cut protection

Designed by CEST in Germany.

The material was developed with our team and our colleagues from a research laboratory in Japan.

The CEST Armor Ultra Pro ballistic undershirt, unisex cut, is woven from a hybrid textile . of only 510 g/m² and a thickness of only 1.2 mm.

• High ballistic holding power
• Various fragment protection
• Highest stab and cut protection

• It can protect the wearer from secondary fragments, minimize injury patterns, and reduce wound contamination.

This ballistic protection system is not equivalent to the German SK 1-4 protective vests  or  US Standard NIJ.

This underwear is used as a supplementary protection, primarily against secondary fragments and explosively accelerated fragments such as dust, sand, and rock particles, which are often found in IEDs.

This material has been tested according to EN 388 6.2-16 ( cut protection level 5 ) and EN 388 6.2-16 ( stab protection level 4 ) by an internationally certified laboratory.

Attention: The CEST Armor Ultra Pro clothing is certified as follows:

Certifications: DIN EN ISO 13688:2013 + EN ISO 13688:2013_A1:2021 (General requirements for protective clothing), EN 388:2016+A1:2018, Ökotex (AITEX 2025EP0132)

Cut resistance (COUP test): Category 3

Test procedure:

A rotating circular blade cuts through the material at a constant speed and constant force (5 Newtons). For simplicity, the result is expressed as an index value. This value is calculated based on the number of cycles required to cut through the material and the degree of wear of the blade used.

Category 0: < Index 1.2

Category 1: ≥ Index 1.2

Category 2: ≥ Index 2.5

Category 3: ≥ Index 5

Category 4: ≥ Index 10

Category 5: ≥ Index 20

*Category X

Stab protection EN 388

A test nail (roughly the size of a carpenter's nail) is pressed onto the test specimen. How much force is required to pierce the material?

Protection level	Required force in Newtons
Class 0	0 to 19.9
Class 1	20 to 59.9
Class 2	60 to 99.9
Class 3	100 to 149.9
Class 4	150+

The great advantage of this ballistic shirt is its comfort. Because it also contains spandex, the fabric is super stretchy and practically wears like a regular undershirt. It's light, thin, and soft, yet breathable and offers excellent stab- and cut-resistant properties.

Bite tests with service dogs (Malinois) have shown that no bite damaged the CEST® Ultra Pro fabric.

Washable (hand wash) at 40 degrees.

Unisex sizes S/M, L/XL, XXL/3XL

Hunting and forestry

We've received very positive feedback from hunters regarding the CEST Armor Ultra Pro clothing. According to their experience, our underwear is excellent for tracking and can prevent injuries from thorny bushes.

Furthermore, CEST Armor Ultra Pro clothing is used in industry (metal and glass processing) due to its very good stab and cut-resistant properties.

Currently, the CEST® Armor Ultra Pro fabric is being tested for certification according to STANAG 2920, V50 FSP (V50, max. 950 m/s, default conditioning) Projectiles: 1.1 g FSP

Important: 

The fabric used in the CEST Armor Ultra Pro collection has outstanding technical properties.

But: This material is not stab-proof (no material is stab-proof or bullet-proof).

It all depends on the shape of the blade and the impact energy. Wearing Ultra Pro clothing can protect you from a knife attack or prevent life-threatening injuries.

Attention: If the fabric is damaged, this clothing loses its protective function.
