Had a presentation by them at our last Blood Bike meeting. The trigger is pretty hard to accidentally set off, and the jacket deflates by itself. You can reset the trigger and replace the CO2 cartridge for £16.00. One of the guys tried it out and it does indeed isolate the neck and head preventing whiplash style injuries and seems to offer protection to the spine, kidneys and thorax. It is similar to the equine ones, except they deploy over twice as fast (according to them) at 100ms vs 250ms. A trigger attaches to the seat via a lanyard that can be unclipped when you get off. I felt it was rather bulky and if you ride with a rucksack or waist pack it can be compromised. I believe that they do a touring style jacket with this integrated. Duke
