Balls may disappear,
Verified Purchase(What is this?)
This review is from: Skins A400 Compression Running Shorts (Apparel)
It claims more room in the groin for "better ball control" (that's the actual wording on the box), but whilst running I have once or twice suffered considerable discomfort as the shorts have compressed so much that a testicle has been forced up inside. The shorts are also too short to reliably prevent chaffing on the upper inner thigh.
That said, I've yet to find anything else that compresses quite so much!
