About KING SupportWear
KING SupportWear makes men's briefs and boxer briefs built around real anatomical support rather than just an ordinary cut. Every pair uses the brand's KingSling system, a six-layer construction anchored into the waistband that lifts and stabilises instead of just covering up.
Alongside that sits the patent-pending CoreLock technology, which keeps everything in place through movement, aimed at men who find standard underwear uncomfortable during sport, travel or an ordinary workday and want something engineered rather than just soft.
