My 80-year-old dad wears it all day long!
My dad is 80, and for his birthday, I got him this vest. He practically lives in it. He has two batteries; one charges while he uses the other. The vest is well made. The first time I bought another, slightly less expensive, but it wasn't nearly as nice. Also, the button is SUPER EASY for him. The other had too many options on the button, and it was confusing for him. Highly recommended for a cold elder! Happy shopping!
