This is kind of a recurring rant of mine, but, why? They’re not really any more comfortable than proper pads, in fact sometimes less so since they tend to be more completely enclosing and are often a bit tighter to keep them in place without the structure of a big pad. And they’re way, way less protective- I have gforms and ime they’re roughly as protective as a thick riding top.
They do fit well under clothes which is a definite plus but imo if it’s worth wearing pads it’s worth doing it properly, and the advantage of the minimal ones is way smaller than you’d expect.
