We currently use the Multifabs suit for our daily trips in the North Sea. It's not the most comportable, but it will allow you to be active for the time needed for the pax. to be gathered. I've tried the suit in the "dunker" course, and you will get wet in a short time. I've also tried a new suit from Multifabs that will keep you "zipped" in at all times. It's better than the former suit but never as great as the ones the pax. are wearing. But you need to be able to function in it, and it can be pretty hot during the summer. I haven't seen any pilot suit making up for both. In addition we use an inflatable vest w/ a beacon and a knife. If you know that you are going to be over water for a long time, use a suit. Better to be safe than sorry...
