Stab Proof Vest Buying Guide: How to Choose the Right Body Armour

Quick Answer: The best stab vest for you depends on three things: your threat profile (knives, spikes, or both), whether you need to conceal it (covert vs overt), and your budget. For most security professionals and civilians, a covert KR1+SP1 vest is the right starting point. Expect to pay £150-£300 for a legitimate certified vest. Below that, certification is unlikely. This guide walks through every decision — covert or overt, FlexGuard or SoftGuard, sizing, legality, care, and the checklist to verify a vest is real — so you can buy with confidence.

What This Guide Covers

Buying a stab-proof vest is not like buying a jacket. The protection has to work when it matters, the fit has to be right for hours of wear, and the certification has to be genuine. This guide walks you through every decision: covert or overt, FlexGuard or SoftGuard, sizing, legality, and long-term care — so you can choose with confidence.

Step 1: Covert vs Overt — Which Is Right for You?

The first and most important decision is whether you need your armour to be visible or invisible.

Factor Covert (Worn Under Clothing) Overt (Worn Over Clothing)
Appearance Invisible — looks like normal clothing Visible — identifiable as body armour
Best for Civilians, plainclothes security, everyday wear, anyone who doesn't want to draw attention Uniformed security, door supervisors, police, anyone who wants the deterrent effect
Comfort Lighter, more flexible, designed for all-day wear under regular clothes Typically heavier with more coverage, worn over a shirt
Coverage Front and back torso — sufficient for most civilian threats Often includes additional side panels, higher collar, groin protection options
Deterrent effect None — attacker doesn't know you're protected Strong — visible armour can de-escalate or deter an attack before it starts
Practicality Wear it anywhere without questions Not suitable for situations where visible armour would be inappropriate or alarming

Our recommendation

  • Choose covert if: You're a civilian wanting everyday protection, a plainclothes professional, or anyone who values discretion. Most ArmorLite customers choose covert.
  • Choose overt if: You work in uniformed security, need maximum coverage, or want the deterrent of visible armour.

Step 2: FlexGuard vs SoftGuard — Choosing Your Armour Type

ArmorLite offers two distinct stab-proof technologies. Both are independently tested to meet KR1/SP1 standards. The differences are in materials, feel, and additional protection characteristics.

Feature FlexGuard Series SoftGuard Series
Stab-proof standard KR1/SP1 (CAST 2017) KR1/SP1 (CAST 2017)
EN388 puncture resistance — 3x Level 4 (450+ Newtons)
EN388 slash resistance — Tested and verified
Construction Flexible layered composite panels Soft, fabric-like multi-layer panels
Feel Lightweight, flexible, more structured feel Soft, flexible, fabric-like feel — closest to wearing a regular garment
Best for Security professionals, situations where maximum stab protection is the priority, wearers who prefer a more structured vest Everyday civilian wear, long-duration comfort, anyone who wants additional puncture/slash protection alongside stab-proof testing standards
Weight Lightweight for its class Comparable — soft construction distributes weight evenly

How to decide

  • Choose FlexGuard if: You want a more structured, traditional armour feel and your primary concern is stab protection. Ideal for security professionals and those who prefer the reassuring rigidity of a layered composite panel.
  • Choose SoftGuard if: You want the most comfortable, discreet everyday armour that also delivers independently verified slash and puncture resistance beyond the EN388 maximum. It is tested to 3 times EN388 Level 4 — the highest rating — and feels like wearing a regular lined garment. This is our recommendation for most civilian buyers.

Step 3: Find Your Size

A poorly fitted vest compromises protection and comfort. The three key measurements are:

  1. Chest circumference — Measure around the fullest part of your chest with a soft tape measure. Keep it snug, not tight. Round up.
  2. Waist circumference — Measure around your belly at navel height. Round up.
  3. Torso length (while seated) — Measure from your collarbone down to 1-2 inches above your belly button. Do this sitting down so the vest won't ride up when you bend or sit.

For the full ArmorLite size chart with FlexGuard jacket, vest, and SoftGuard measurements, see our Size Guide.

Quick tip: Body armour sizes do not correspond to your clothing size. Always measure. When in doubt, size up — most vests have adjustable shoulder and waist straps.

Step 4: What Protection Level Do You Need?

For most buyers, this is the simplest decision:

  • KR1 + SP1 (Level 1): The standard recommended by the UK Home Office for patrol officers in general-risk areas. Tested to withstand 24 Joules of knife and spike force. This is the right level for civilian wear, security work, and everyday protection.
  • KR2 + SP2 (Level 2): Higher protection at 33 Joules. Adds weight and reduces flexibility. Only necessary for medium-risk operational environments.
  • KR3 + SP3 (Level 3): Maximum protection at 43 Joules. Heavy, less flexible, designed for short-duration wear in high-risk scenarios. Overkill for civilian use.

Our recommendation: KR1 + SP1 is the appropriate level for virtually all civilian and security buyers. It is what UK police wear on patrol. Unless you have a specific operational reason to need Level 2 or 3, Level 1 is the right choice. For a deeper dive into what these certifications mean, read our Body Armour Certification Guide.

Step 5: Legal Considerations

Body armour laws vary by country. Here is a summary of the key jurisdictions. This is not legal advice — verify the current laws in your location before purchasing.

United Kingdom

Legal. No licence or permit required. Stab-proof and bullet-resistant body armour is classified as protective equipment, not a weapon. You can legally purchase, own, and wear body armour in public for personal protection. However, wearing body armour while committing a crime may be treated as an aggravating factor in sentencing. Exporting body armour from the UK requires an export licence.

European Union

Body armour is generally legal for civilian ownership across most EU member states, including Germany, France, Spain, Italy, and the Netherlands. Some countries may restrict wearing body armour during public demonstrations or in specific contexts. Check local regulations in your country.

United States

Legal for law-abiding citizens in most states. There is no federal restriction on purchasing or wearing body armour. Connecticut restricts online sales (in-person purchase only), and convicted felons are prohibited from possessing body armour under federal law. Some states have additional restrictions — check your state's laws.

Canada

Restricted. Several provinces (including Alberta, British Columbia, Manitoba, and Ontario) require a permit or licence to possess body armour. Permits are typically issued to those with a demonstrated occupational need (security, law enforcement). Check your provincial regulations.

Australia

Restricted. Regulations vary by state. Several states (including Victoria, Western Australia, and South Australia) restrict or prohibit civilian ownership of body armour without a valid occupational reason. Check your state's specific legislation.

New Zealand

Generally legal. No specific ban on civilian body armour ownership, though restrictions may apply in certain contexts.

ArmorLite primarily ships to UK customers. If you are ordering from outside the UK, you are responsible for ensuring compliance with your local laws. Contact us for clarification on international orders.

Step 6: Care and Maintenance

A well-maintained stab-proof vest lasts 5 years or more. A neglected one can fail without warning. The single most important rule:

Always remove the armour panels from the outer carrier before cleaning. Never machine-wash, soak, or submerge the protective panels.

Quick care summary:

  • Outer carrier: Machine wash cold, gentle cycle, mild detergent. No bleach, no fabric softener. Air dry or tumble dry low.
  • Armour panels: Spot clean only with a damp cloth and mild soap. Wipe dry immediately. Never submerge.
  • Storage: Hang on a padded hanger in a cool, dry place. Never fold, crease, or place heavy objects on the panels. Keep out of direct sunlight.
  • Inspection: Check before every wear for tears, fraying, delamination, or visible damage. If the armour looks damaged, do not wear it — contact us.

Step 7: What to Look For When Buying

Whether you buy from ArmorLite or another supplier, here is your checklist:

  1. Ask for the test report. Any legitimate seller can produce a test report from a named, accredited test house. If they cannot, the armour has not been independently verified.
  2. Check the standard. It must name the specific standard — CAST 2017, HOSDB 2007, or NIJ 0115.00 — and the level achieved. "Tested to KR1 standards" without a test report is not the same as verified.
  3. Verify the test house. In the UK, accredited test houses include NTS (National Technical Systems) and SATRA Technology. A test report from an unknown or unaccredited lab is not valid.
  4. Check the label inside. UK-tested armour must carry an internal label with manufacturer name, model number, batch number, protection level, and test house reference.
  5. Know what you're getting. "Stab-proof" does not mean bulletproof. "Puncture-resistant" does not mean stab-proof. Confirm which threats the armour has been tested against.
  6. Try before you rely on it. When it arrives, wear it. Sit, bend, reach, drive. Make sure it fits and you can function in it. A vest that's uncomfortable in your living room will be unbearable on an 8-hour shift.

Frequently Asked Questions

Is a stab-proof vest uncomfortable to wear all day?

A well-fitted, quality stab-proof vest should be comfortable for all-day wear. Modern materials like ArmorLite SoftGuard panels are soft and fabric-like — many wearers report forgetting they have it on after the first hour. The key is correct sizing and choosing the right product for your use case.

Can I wear a stab-proof vest under a shirt?

Yes — this is exactly what covert vests are designed for. ArmorLite products are built to be worn under regular clothing, including t-shirts, shirts, and jackets. Our SoftGuard series is specifically designed for maximum discretion under light clothing.

How long does a stab-proof vest last?

The industry standard service life is 5 years, subject to proper care and regular inspection. Factors that reduce lifespan include daily wear, exposure to moisture and UV, poor storage, and lack of cleaning. A well-cared-for vest stored in cool, dry conditions can last beyond 5 years, but manufacturers typically recommend re-testing after this period.

Does a stab-proof vest protect against bullets?

No. Stab-proof and bulletproof are entirely separate protection categories using different materials and construction. A KR1/SP1 vest protects against knives and spikes — it will not stop a bullet. If you need ballistic protection, you need a vest tested to meet NIJ or HO1 standards, which is a separate product category.

Do I need a licence to buy body armour in the UK?

No. Body armour is legal for civilians to purchase, own, and wear in the UK without any licence or permit. It is classified as protective equipment, not a weapon.
