Good point, something to think about is size or how much room you have left inside your race suitKnox or ForceField depending on how fat I am that day. ;-)
If you follow the Cambridge University Independant test. The Forcefield Sub 4 is the best back protector on the Market. The next is the Forcefield L2.
The Sub 4 is the only back protector to absorb the greatest impact of all the back protectors tested. Which is a lot.
Keep in mind, some back protectors are only able to absorb one impact. Also you can't prevent hyperextension with a back protector design we currently see. So impact absorbtion is Cambridge University's basis for the test. Meaning hard plastic won't absorb much. So the best value is a multi hit product with as much impact absorbtion as you can get.
L2 test
The Forcefield back achieves and surpasses level 2,the highest pass possible against the latest European draft standard ref: prEN1621 - 2 `which is officially known as "Motorcyclists Protective Clothing against mechanical impacts - Part 2" i.e. Motorcyclists Back.
SATRA Technology Centre in the UK has stringently tested the Forcefield Back. CE documentation and performance tests are fully approved and supported by SATRA. All production is continually monitored both in the UK and Asia. By our working closely with `SATRA Technology Centre` and the `Protective Clothing Research Facility` at Cambridge University gives the consumer assurance that Forcefield down to its finest detail conforms to the latest CE requirements.The latest testing by SATRA of the Forcefield back protector transmitted only 4.93Kn to the body. (The maximum transmission allowed for level 2 is 9Kn). This is the ultimate in protection and comfort.
Sub 4
The Pro Sub4 is the highest performing back protector available.
The Official CE tests show a true CE reading of 3.38kN, making this unique in the
marketplace.
A back protector with all day comfort, repeat performance and impact protection that is truly
market leading. A world First.
Over the 7 impacts incurred during the CE test, not one impact was above the 4kN mark.
Showing safety and consistency across the entire product.
4kn is considered by medical experts to be the maximum amount of transmitted energy that
should be subjected to a human to prevent severe back and rib trauma.
Why not buy local? with exchange rates and delivery you are probably better off (if someone sells it)Thanks guys, have to admit the Sub 4 had caught my attention from studies stating the Kn that vertebrae can take before fracture in a direct impact.
Pricing seems to be $180- $200US on EBay.
