I have a copy of the summary of the test data carried by the Transport Research Laboratory. Message me if you'd like a copy.
I emailed Point Two asking them if you need to wear a body protector with their jacket. This was their response:
With regards to the ProAir jackets being a standalone product, it was actually designed for use with motorcycles. Obviously you would not use a body protector whilst riding a motorbike. The reason we recommend you use the ProAir in conjunction with a body protector is to ensure you are as safe as possible at all times whilst you are around your yard and horse. The ProAir jacket is designed to offer support to the rider in a fall situation, once it has been inflated. However it will only be able to offer you a minimal amount of protection whilst you are walking around your yard, if your horse was to kick you for instance. Where as a standard body protector would be able to offer you this protection. Secondly if in the very unlikely event that your air jacket was to fail the standard body protector would be there as a backup.
