Launched in 2012 and featuring all-new dual-compound hybrid technology, a unique four-plate structure, the Knox Meta-Sys back protector is updated and improved for 2015. The new Meta-Sys back protector offers more protection, less weight and is fully certified to level two of the latest CE standard.
The Meta-Sys is constructed using a ’hard’ polypropylene outer shell to dissipate impact, combined with a lightweight Nitrex inner layer for superior energy absorption and protection against multiple impacts. It exceeds Level 2 of the tough new EN 1621-2:2014 back protector standard; the mean transmitted force is less than 6kN in each of the 10 tests. In fact some tests showed just 3kN. The Meta-Sys offers the same level of protection in extreme temperatures, ranging from -20 to +40C, something that few other protectors achieve.
This increased protection hasn’t come at the expense of weight; the 2015 Meta-Sys weighs just 1.08kg. Lighter than most full carbon motorcycle helmets.
EN 1621-2:2014 assesses the performance of protective devices by measuring the force transmitted through it when impacted by a falling mass of 5kg. Protectors subjected to the test are deemed to conform to the standard if the average transmitted force of 10 tests is less than 18 kN for Level 1 protectors and 9 kN for Level 2.
