The seat belt buddy is not only made for comfort whilst wearing your seat belt but is the place to store essential information if an emergency should crop up. 
The buddy has 3 layers, cotton fabrics and wadding to give it that luxurious feel to enhance your journey. The pocket is optional but in an emergency could be essential. Pop relevant details on the back of a card and slide it into the pocket,  including any medical issues or allergies and information of any pets left alone at home. 
Make your self one or make one for all the seat belts in your car so your passengers are safe and comfy too.
