These protectors of manhood come in all shapes, sizes, materials, colors, quality, and effectiveness. They have to be safe, high quality and effective. So what makes a cup "good"?
A traditional groin cup gives you plenty to think about: will it be so uncomfortable; you’ll avoid wearing it? (In many cases, yes.) Will its sheer bulk and weight impede your movements? (Probably.) Will it break? (With some composites, maybe.) Will you be dropping your guard to readjust it over and over? (Very likely.) Will it follow your every move, providing 100% protection whether you are standing, kicking, riding, jumping or wrestling? (No.)
Everyone has seen it. A guy takes a hard hit to the balls in sports and we all groan and think “Wow, I hope he had his cup on”. But what about women?
The testicles are designed to register pain to force us to protect them and prevent injury. And that is what an athletic cup does.
The testicles are exactly where you would get kicked in many sports, and their location on the body makes them quite challenging to protect even if we were standing still. But body movement in sports makes that far more difficult.
