I've had one of these now for a few months. First PFD I've bought and used. Checked out feedback here on SB before choosing it. Comments on here were that they don't ride up. What am I doing wrong? I can't stop the bloody thing riding up. I'm sick of having the top of the thing pushing up under my throat the whole time while sailing. Is it an option to secure the thing to my harness? I use a seat harness and the bottom of the vest happily contours at the back, fitting in perfectly with the top of my harness before setting off. I want to keep using it. Any helpful suggestions would be appreciated.
