That might allow your underwear to last a bit longer, but there's no real reason to wear them underneath athletic underwear. Althletic underwear already has the support built in.
That's pretty much the purpose behind athletic undies. You have the coverage of normal undies, the sweat wicking of athletic shorts, and the support of a jock strap. Best of all worlds.
Wearing this without underwear seems nonsensical, the ass sweat would just ruin your pants and be disgusting. Especially if you had taken a dump that day
