I bought the Ralley Pro 3 earlier this year. Mine was fine while I had a K1200GT as the fairing kept the weather away. The GS was a different story mine leaked at the front from the chest down. Never managed to find where the ingress of water was from but I got very wet.
The second and for me the most annoying problem was the weight. I have never owned a jacket that was so heavy. I took it back to Pidcocks and got a full refund. As is usual, in my experience, great service from Pidcocks.
Now got a Rucka Marco Jacket and matching trousers. What can I say other than I would take some convincing to buy a BMW 'Twat' jacket again.
Used the Rucka gear extensively and very, very impressed. Not as warm as the BMW gear, but that is an advantage for half the year and I can do something about the cold.
