Boxer briefs with shaped padding through the seat, plus compression at the waist.
Who buys these
Men who want a fuller shape through the back of a pair of trousers or jeans. It is a common enough thing to want that the category exists — it is just rarely discussed openly, which is why most listings for it are vague.
Fit
Contoured padding built into the seat, not a removable insert that shifts
Firm compression at the waist for a flat front line
