CEST® Armor Ultra Pro ballistic undershirt long stab protection cut protection

Designed by CEST in Germany.

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

The ballistic CEST Armor Shirt Ultra Pro, unisex cut , is woven from a hybrid textile (including Armortex, fiberglass, HPPE), 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 (small fragments, sand), 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 ( highest cut protection level 5 ) and EN 388 6.2-16 ( highest 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

EN 388 stab protection

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+

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

Color: white or gray

The biggest advantage of this shirt is its comfort. Because it's made with spandex, among other materials, the fabric is super stretchy and actually wears like a regular undershirt. It's light, thin, and soft, yet it's breathable and offers excellent cut- and stab-resistant properties.

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 significantly reduces injuries from thorny bushes.

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

Important: 

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

But: This material is not puncture-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.

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
