I use it on my driver's seat belt. Not a game changer, but definitely more comfortable. It is a good buy.

I got my seat belt covers last week, and they definitely make the seat belt softer against my neck and shoulder! I am happy to find something to protect my skin this summer when I wear sleeveless tops. The covers are sheepskin feel and have nice Velcro closures. They will slide on the seat belt as you get in and out of the car so you don't have to take it off each time. My only reservation is how well the fluffy fabric will stay that way and remain soft.

ok

keeps belt from rubbing the neck, great!
