02 — Frequently asked questions

Frequently asked questions

These answers summarize the most common questions about protection levels, sizing, maintenance, ownership, travel and everyday use.

Topic 01

Protection levels

What ballistic protection standards do you follow?

Our products are tested according to multiple internationally recognized standards: NIJ (National Institute of Justice, USA), VPAM (Germany), and HOSDB (UK). This multi-standard approach ensures our armor meets requirements across different markets and provides transparent, verified protection levels. Each product listing specifies which standard applies.

What's the difference between soft armor and hard armor?

Soft armor is flexible, made from woven or laminated ballistic fibers (typically aramid or UHMWPE), and designed to stop handgun rounds and knife attacks. It's lightweight, concealable, and comfortable for daily wear. Hard armor consists of rigid ballistic plates (ceramic, steel, or polyethylene composite) that defeat rifle rounds and armor-piercing threats. Hard armor is heavier and less flexible but provides higher protection against rifle-caliber ammunition.

What protection level do I need for everyday personal protection?

For most civilian self-defense scenarios and private security work, NIJ Level IIIA soft armor is the practical choice. It stops virtually all common handgun threats (up to .44 Magnum) and provides stab resistance, while remaining comfortable enough for extended wear. Handgun and knife threats represent over 90% of civilian violence scenarios in most countries.

When do I need hard armor plates (Level III or IV)?

Hard armor is necessary when facing rifle threats. Level III defeats common rifle rounds (7.62x51mm NATO, 5.56x45mm), while Level IV stops armor-piercing rifle ammunition. Military personnel, tactical law enforcement units, and individuals in high-risk conflict zones typically require hard armor. For civilian use, hard armor is generally only justified in areas with active armed conflict or documented rifle-caliber threats.

Can I wear soft and hard armor together?

Yes. Many of our systems allow you to combine a soft armor vest (NIJ IIIA) with hard armor plate inserts. This provides comprehensive protection: the soft armor covers a larger body area against handguns and fragments, while hard plates in front and back protect vital organs against rifles. This is a common configuration for security professionals and high-risk environments.

Does heavier armor mean better protection?

Not necessarily. Weight depends on materials, size, and coverage area, not just protection level. Modern UHMWPE (polyethylene) plates can provide Level III or IV protection at half the weight of steel plates. A 3kg ceramic plate might offer better protection than a 6kg steel plate. Focus on the protection level and consider weight as a factor for comfort and mobility, but don't assume heavier automatically means safer.

What's the difference between "ballistic protection" and "stab protection"?

Ballistic protection stops bullets and projectiles using materials that absorb and disperse kinetic energy. Stab protection prevents knife and spike penetration using tightly woven or layered materials that resist cutting and puncture. Some soft armor provides both (like our NIJ IIIA systems), but they are different threats requiring different material engineering.

Topic 02

Sizing and fit

Why is correct sizing so important for body armor?

Proper fit is critical for both protection and usability. Armor that's too large shifts during movement, leaving vital organs exposed and creating gaps where rounds can penetrate. Armor that's too small doesn't cover essential areas like the heart, lungs, and major blood vessels. Incorrect sizing also causes discomfort, restricts breathing and movement, and leads to fatigue — which can compromise your safety and performance in critical situations.

How do I measure myself to find the right armor size?

Compare your measurements to the size chart on each product page. If you're between sizes, consider your body type and intended use — if you have a broader torso or plan to wear the armor over thick clothing, size up. For concealable use with tight clothing, stay with the smaller size if you're borderline.

What body areas should armor cover for adequate protection?

At minimum, armor must cover:

  • Front: From the sternal notch (top of breastbone) down to at least 2-3cm below the navel, and side-to-side from nipple line to nipple line.
  • Back: From the top of the shoulder blades down to the lower ribs, covering the spine and both sides of the ribcage.

This ensures coverage of the heart, lungs, liver, kidneys, spleen, and major arteries. Armor should not extend too far down — excessive length restricts sitting and bending. Proper fit means full vital organ coverage without sacrificing mobility.

Should armor fit tight or loose?

Armor should fit snug but not restrictive. It should stay in place during movement without shifting, but allow full breathing and a natural range of motion. You should be able to raise your arms overhead, bend forward, and sit down without the armor riding up or digging in. When properly adjusted, there should be minimal movement when you twist your torso.

Do hard armor plates and soft armor require different sizing?

No. Our armor panels (soft or hard) are sized to match the carrier/vest size. If you order a Medium vest, the Medium soft armor panels or hard plates are designed to fit that carrier. You don't need to size them separately. However, coverage area may differ slightly — hard plates typically protect a smaller, more focused area (center mass) compared to soft armor, which offers broader coverage.

Is there a difference in fit between men's and women's armor?

Currently, we offer unisex sizing (S/M/L/XL) that fits most body types. Our adjustable systems accommodate different torso shapes and proportions. In the future, we may introduce female-specific designs with contoured cuts, but our current range is designed to provide effective protection and comfort across all users when properly sized and adjusted.

Can I return or exchange armor if the size doesn't fit?

Yes. We understand that sizing can be challenging when ordering online, especially for a product as critical as body armor. If the size doesn't fit correctly, you can return or exchange it according to our return policy. We recommend trying the armor on immediately upon receipt (over clothing) and contacting us within the return window if adjustments are needed.

Topic 03

Care and use

How long does body armor last?

Our ballistic panels (both soft armor inserts and hard plates) have a rated lifespan of 10 years from the date of manufacture, provided they are stored and maintained correctly and have not sustained ballistic impacts. The textile carriers (vests) have a lifespan of approximately 2 years due to wear on fabric, stitching, Velcro, and straps from regular use. The ballistic protection itself lasts much longer than the carrier—you can replace the carrier while continuing to use the same panels if they remain within their service life and show no damage.

Does armor expire even if I never use it?

Yes. Ballistic materials degrade over time due to environmental exposure, even in storage. UV light, temperature fluctuations, humidity, and oxidation gradually reduce the molecular integrity of aramid and UHMWPE fibers, and ceramic or composite plates can develop micro-fractures. A 10-year-old panel that has never been worn is still at the end of its safe service life and should be replaced. Always check the manufacturing date on your armor and retire it after 10 years, regardless of condition or use.

Can I wash my body armor?

You can wash the carrier (vest) only — never the ballistic panels themselves. Remove all soft armor inserts and hard plates before washing. Hand wash the carrier in cold or lukewarm water with mild detergent (no bleach, no harsh chemicals). Gently scrub stains with a soft brush if needed. Rinse thoroughly and air dry completely — never machine dry, tumble dry, or use direct heat. Do not wash ballistic panels, as water and detergent can damage the ballistic fibers and delaminate layers, compromising protection.

How do I clean the ballistic panels if they get dirty or sweaty?

Ballistic panels should not be submerged in water or washed. If soft armor panels develop odor from sweat, remove them from the carrier and air them out in a well-ventilated area away from direct sunlight. You can gently wipe the outer surface with a damp cloth (water only, no chemicals) and allow to air dry. For hard plates, wipe the surface with a damp cloth if needed.

How should I store body armor when not in use?

Store armor in a cool, dry, dark place with stable temperature and low humidity. Ideal conditions:

  • Temperature: 15-25°C (avoid extreme heat or freezing)
  • Humidity: Below 60% relative humidity (avoid damp basements or humid environments)
  • Light: Away from direct sunlight and UV exposure
  • Position: Store panels flat or hanging vertically—never folded, rolled, or compressed under heavy objects

Store armor in a breathable bag or on a shelf, not in airtight plastic containers (which trap moisture). Keep away from chemicals, solvents, gasoline, oils, and cleaning agents. Avoid storing in hot vehicles, attics, or outdoor sheds where temperature swings are extreme.

How should I clean and maintain my body armor?

Clean carriers with mild soap and water and let them air dry. Inspect armor regularly for visible damage, delamination or cracks. Store armor in a cool, dry place away from direct sunlight and excessive heat.

What happens if armor takes a hit? Can I still use it?

No. Body armor is designed to stop one hit per area, not multiple. After a ballistic impact, the panel has absorbed and dispersed massive energy, causing internal damage to fibers or ceramic layers that may not be visible externally. The compromised area and potentially the entire panel will not reliably stop a second round. Replace any armor that has sustained a ballistic impact immediately, even if it "looks fine." This is non-negotiable for your safety.
