THK Knox Jock

Sleek. Minimal. Built for speed.

The THK Knox Jock is the stripped-down, high-definition essential for the man who prefers a lighter, faster, more minimal silhouette. Featuring a streamlined 1" waistband, the Knox delivers a sharp, athletic look without the bulk—perfect for training, layering, or showing off your hard-earned physique.

Crafted from THK’s signature performance stretch blend, the Knox Jock offers a breathable, supportive fit with a contoured pouch designed for lift, comfort, and natural shape. Reinforced straps define the glutes with precision, while the low-profile waistband sits comfortably on the hips for an effortless, barely-there feel.

Strong lines. Clean construction. Maximum confidence.
