No, the JR Speedmaster is the same as the T-pro Forcefield which is CE EN1621-2 Level 2 approved, though JR is stupidly not advertizing that fact. I have email confirmation that it is the same level 2-rated piece as the T-Pro. The Astars Tech(not Race) is CE approved, but only to Level 1 of that standard. It's confusing because the CE motorcylist limb impact protector standard is EN1621-1, and the motorcyclist back protector standard is EN1621-2, with two levels of passing. The JR/T-Pro is one of the best pieces available for specific motoryclist back protectors. In testing, it has shown passing those requirements at 6.5kN, the standard calls for 9kN(@50J) for level 2 approval, the Alpinestars Tech has been shown at 14.5kN, Level 1 allows up to a [email protected]
average. So the JR transmits much less force to the body. However, both levels are compromised, as it only takes 4kN of force to break ribs and cause bruising, according to the medical evidence. The equestrian rider's standards properly use the 4kN mark for a passing minimum, and create levels of performance based more appropriately on the impact energy that a piece can manage down to those levels of force transmission. The BETA 2000 Level 3(purple label) standard uses 45J for those rated body protectors, which are likely some of the most protective riding vests available, due to the allowable force transmission and an extended coverage area which includes ribs, kidneys, clavicle, and chest areas. Those vests are realtively inexpensive too, may be worth a look, the Airowear and Tipperary Esprit vests are under $150 for that complete front and back coverage.
