I have the cool guard I like them because they are easy to slip in and out. The problem though I had is I am well in endowed, so I had to get the largest size in the plastic guards and it still was not big enough and the sports bra that came with it was to big for me, way to big, go figure. But I hope with my recent weight loss and hopefully the continue weight loss that the will fit better. But back to them being to small they left small bruises when I got hit in them but it was a very hard hit and I did not feel a thing, it was very nice for a change. Ya, what is up with teenage boys. That seems to be the only place that they want to hit at and when they do they laugh about it every time they hit there, at least in my experience. But let them hit them guards bare handed it will not be pleasant for them.
