This IS for men, not women
Poltech Thumbsaver Large Male Blue
I saw the review about the man who is over 6' tall and since he said his wife put this on with no wiggle room, I bought it. However, it's so big it falls off my thumb. My dad put it on and it fit his thumb perfectly. Maybe that guy and his wife have extra large hands or thumb joints? If you're a woman, don't order this.
