Knox is renowned for its armour - Knox's Micro-Lock Chest protector is CE certified to EN 1621-3 and offers a soft and snug fit to the wearer, but Knox's SMART technology locks in the event of an impact and absorb a large proportion of the energy before it gets to the wearer. It is low-profile and moulded for excellent comfort with a breathable perforated design for maximum ventilation - the mesh cover is also removable and washable. It also features a smart fixing system on the front that allows the chest protector to be fitted to a Knox back protector and is fully adjustable for a supremely comfortable fit. Please note that the straps/waist belt aren't included and are actually the Knox Back Protector sold separately.
