Public Order Helmets

MLA design and manufacture a range of public order helmets and ballistic helmets. All out public order helmets are built to HOSDB standard. Our Defender public order helmet is part of the National Framework Contract.

We also offer a range of optional extras including visors, helmet bags, torch mounting systems and belt mounted helmet carriers.

The MLA range of public order and anti-riot Helmets are intended for Police use for public order duties.

All our police helmets have been tested to PSDB Publication No. 21/04.
MLA Public Order Helmets offer protection against manual attack weapons and injurious and flammable liquids.

PLEASE NOTE; Public Order Helmets and anti-riot helmets offer NO PROTECTION against ballistic attack.

The visor is formed from 3MM polycarbonate, and is anti-fog (AF-1140) coated.

We also offer a range of optional extras including visors, helmet bags, torch mounting systems, helmet bags and belt mounted helmet carriers.

The assembly and construction of the ‘Defender’ public order helmet was brought in-house in 2014.

A new improved helmet; 'Merlin', will also soon be put into production at MLA's helmet assembly plant in Yorkshire.
