I bought it extra for a 2 week trip. Always worn when driving at night. Great freedom of movement and comfort. I still have to get a service kit because one was not included. The only (but as with all other manufacturers) shortcoming is that a service kit has to be bought separately. In the event of a release, you should always have a service kit with you. I had to learn too.
Safety for everyday use, easy to act, on duty every time you leave the cockpit. Lifeline carabiner should be easier to handle (with cold hands in rough water)
There is no metal D-ring for the Life-Line, there is a red band to hook it on, in my opinion not as easy to handle as a rigid ring. For me the adjustment range is too small when I put on a thick bad weather jacket.
