When I first saw Paul’s photo (below) I initially thought that the PFD looked like a FX or FX R in a funky new colour. But there is clearly a different zip and an additional zipped side pocket.
The jacket looks new as well!
A bit more digging has found what looks like the same PFD in a video we posted from Bren Orton a little way back. These screen shots from the video definitely show a prototype or new design of PFD and not the original FX/FX R.
The main zip is way longer than the one on the FX or FX R and there is definitely some additional zipped storage either side.
The quick release from the rescue belt is located on the left and it appears that the is pretty much concealed. The QR on the FX R is located on the right.
