MOMENTUM Innerwear Jammer Underwear - Black

Essential black jammer with all-day performance. The MOMENTUM Innerwear Jammer - Black (MCMI3422BT) by Private Structure is the ultimate staple for the modern man. Featuring a functional long-leg "jammer" cut, this underwear extends down the thigh to provide superior coverage, preventing chafing and ride-up whether you're at the gym or on the move.

Soft cotton-stretch blend for daily comfort. Part of the "Innerwear" line, this jammer is crafted from a premium blend of 95% cotton and 5% spandex. This fabric combination offers the natural softness and breathability of cotton with the necessary stretch to move with your body, ensuring a secure yet non-restrictive fit throughout the day.

Sleek athletic design. The classic black body is complemented by a sporty branded waistband that sits comfortably on the waist without digging in. The engineered contoured pouch provides optimal space and support, keeping everything in place while delivering a sharp, masculine silhouette.
