Every time my missus or mother in law sit in the back of my Sport they complain about the seat belt cutting across their neck.
I know the belt comes very low but does anyone know of anything that would go on the belt to ease the pain. Or shall I just tell em to stop moaning! 3.0 HSE RRS Stornaway (current)

I had the same problem many years ago in my V40, it used to cut into my daughters neck.
The only visually pleasing solution I found was a very unobtrusive seat belt pad that pretty much matched the colour of the seatbelt.

I did find some things that pulled the belts together more but they were all in rather bright or luminous colours!.
Hope this helps a bit. Need....more.....mud, must.....off.....road.
