I just googled this and am embarrassed for the designer.... What a pillock you would look with one of these on the first tee , wearing bright yellow (or lime green ) trousers and a pink J Lindberg hat. 

And people used to get a hard time for wearing wooly jumpers. I don't know how this world works.... 

erm I have one,was struggling to get the weight shift with my swing and the pro had one fitted with a training grip,seems to have worked well for me and it is great for swatting wasps too.

ah... so that's why people swing a hand full of irons in the warm up to the first tee....

Tempo...tempo...tempo...
