The Forcefield Pro Sub 4 was specifically designed to test at under 4kn transmitted energy when subjected to the standard CE test EN1621-2.
4kn is considered by medical experts to be the maximum amount of transmitted energy that should be subjected to a user to prevent severe back and rib trauma.
Independent testing by SATRA shows a mean test result of 3.38kn making it the first motorcycle back protector in the world to attain this level of performance.
The Forcefield Pro Sub 4 back protector is constructed with a removable & washable outer cover; this gives the user the ability to keep the cover clean and hygienic. It also makes the protector more flexible as it is not bonded at the edges, this in turn makes it more comfortable, a prime consideration when Forcefield design any protector, it is know that if a protector isn’t comfortable it will not be used or could be distracting and dangerous for the user.
As with all Forcefield Body Armour the Pro Sub 4 has RPT (Repeat Performance Technology) ensuring continued and consistent protection even after multiple impacts.
