10 Year WarrantyWarranties

Fortis ® are the UK’s leading manufacturer of stab vests and ballistic vests to local authorities, the NHS, government departments and blue chip companies. We work at the cutting edge of technology, and our body armour is the lightest, most flexible and therefore most comfortable in the industry, whilst still meeting all Home Office & CE Mark standards.


The Warranty Period


Stab & Spike Resistant Vests

We are pleased to announce that after careful consultation with our raw material suppliers and rigorous age-testing, the Warranty Period on our Fortis® KR1/SP1 stab and spike protective vests is 10 years, after which period of time it should be replaced.


Multi-Purpose (Ballistic, Stab & Spike Resistant Vests)

Armour that is multi-purpose (that is, handgun, knife and spike resistant HG1/KR1/SP1 or higher) carries an initial 5 year warranty; after this period it can be checked and recertified for a further 5 years for a modest cost (similar to an MOT on a car) to give a total life of 10 years.

The armour panels have to be replaced after this period even if they are not damaged because the material used in the vest will, over time, degrade. Remember, these are PPE items and they may be called on to prevent serious and life threatening injury and be subjected to extreme trauma. Put another way, you would not speed around a race circuit at 200mph on a high powered motorbike, knowingly wearing a 10 year old crash helmet that had been generally abused and mistreated.

We have a duty of care and a responsibility to the users of our products – as do our material suppliers – as do you - and we know that over a period of time the efficiency and performance of any material will tail off. That decay will be gradual, not seismic, but there WILL be a fall-off in performance. We build in to our calculations massive safety margins and, to cover everyone in the chain, from the raw material supplier right the way through to the end user, we, (as do all reputable body armour manufacturers) stipulate a ‘best before’ date.
